According to various embodiments, the processor 410 is connected to the connector 450 based on the second terminal 453 (e.g., GND (B12) terminal, GND (B1) terminal) included in the connector 450. It is possible to determine whether moisture has entered. According to one embodiment, the processor 410 may switch the moisture detection module 411 to be connected to at least one of the GND (B12) terminal and the GND (B1) terminal through the switch unit 430, The resistance detection voltage can be measured in response to at least one of the GND (B12) terminal and the GND (B1) terminal. The processor 410 may use the switch unit 430 to measure the resistance detection voltage by alternating between the GND (B12) terminal and the GND (B1) terminal. For example, the processor 410 may control the power supply module 420 to apply a pull up (PU) voltage to at least one GND terminal. The moisture detection module 411 may measure the resistance detection voltage corresponding to at least one GND terminal while the PU voltage is applied.

The moisture detection module 411 may determine whether moisture has entered the connector 450 based on the measured resistance detection voltage. According to one embodiment, the processor 410 can determine whether moisture has entered the connector 450 based on the measured resistance detection voltage, and controls the power supply module 420 when moisture has entered. Thus, the PU voltage value can be adjusted. For example, if it is determined that moisture has entered, the processor 410 can lower and apply the PU voltage value used in the moisture detection operation and prevent corrosion due to the inflow of moisture.

According to various embodiments, the processor 410 may control the power supply module 420 and set the voltage (e.g., PU voltage) provided by the power supply module 420 to about 3V or about 1.5V. there is. According to one embodiment, the voltage provided by the power supply module 420 is not limited to about 3V or about 1.5V. For example, when the PU voltage is set to about 3V and the PU voltage is applied through the power supply module 420, if moisture does not flow into the connector 450, the moisture detection module 411 detects the resistance voltage. About 3V can be measured. For example, when moisture flows in, the resistance value may be lowered due to the introduced moisture. According to one embodiment, when the PU voltage is set to about 3V in the power supply module 420 and the PU voltage is applied to the connector 450, if moisture flows in, the measured resistance This may be lowered. According to one embodiment, the processor 410 can measure the resistance detection voltage through the moisture detection module 411, and due to the introduced moisture, the measured resistance detection voltage is measured as low as about 1V or less. It can be. According to one embodiment, the moisture detection module 411 may determine whether moisture flows into the connector 450 based on the measured resistance detection voltage.

According to various embodiments, in order to prevent the determination of moisture conditions and dry conditions from being reversed based on a specific impedance value, the processor 410 controls the power supply module 420 to change the setting of the PU voltage. there is. For example, if the PU voltage is set to about 3V and the resistance detection voltage is measured to be less than about 1V, it can be confirmed that moisture has entered the connector 450. When there is moisture in the connector 450, the resistance value may be about 1.5 Mohm. For example, in the process of evaporation of moisture flowing into the connector 450, the resistance value may fluctuate around 1.5 Mohm (e.g., a ping-pong phenomenon). According to one embodiment, the processor 410 may change the PU voltage from about 3V to about 1.5V by controlling the power supply module 420 to reduce the occurrence of the ping-pong phenomenon. For example, when the PU voltage is set to about 1.5V and there is moisture in the connector 450, the resistance value may be about 6 Mohm. As the resistance value increases, the occurrence of the ping-pong phenomenon may decrease.

According to one embodiment, when the PU voltage applied to the connector 450 is set low, the occurrence of corrosion due to introduced moisture may be reduced.

Resistance detection voltage = 1V standard PU 3.0V PU 1.5V Moisture detection conditions (WET) 1.5 Mohm Dry detection conditions (DRY) 6 Mohm

Referring to Table 1 above, it shows resistance values corresponding to moisture conditions and dry conditions according to changes in PU voltage. According to one embodiment, when the resistance detection voltage measured through the moisture detection module 411 is measured to be less than about 1V while the PU voltage is set to about 3V, the processor 410 determines that moisture has entered the connector 450. You can judge. The fact that moisture has entered the connector 450 may mean that moisture has come into contact with at least one of the GND (B1) terminal or the GND (B12) terminal. The processor 410 may measure the resistance detection voltage in response to at least one of the GND (B1) terminal or the GND (B12) terminal. For example, if moisture flows into the connector 450, the resistance detection voltage value may drop to less than about 1V due to the resistance component caused by the moisture, and the moisture detection terminal (e.g., connector) in the moisture-inflowed state may drop. (210) The resistance value between the GND (B1) terminal or GND (B12) terminal on the B side) and the ground terminal (e.g., GND (A1) or GND (A12) on the A side of the connector (210) is about 1.5 Mohm or less. You can.

According to one embodiment, when the moisture sensing terminal is dried with moisture flowing in, the resistance value of the moisture sensing terminal may change around 1.5 Mohm. (Repeatedly based on a resistance value of about 1.5 Mohm. It may become larger or smaller.) According to one embodiment, the processor 410 may repeatedly determine the inflow of moisture or evaporation of moisture in response to the connector 450. It may be difficult for the processor 410 to precisely determine whether moisture has entered.

According to one embodiment, in order to precisely determine whether moisture has entered, the processor 410 may control the power supply module 420 to reduce the setting of the PU voltage from about 3V to about 1.5V. For example, when the PU voltage is set to about 1.5V and the resistance detection voltage corresponding to at least one of the GND (B1) terminal or the GND (B12) terminal is measured to be about 1V or more, the processor 410 connects the connector It can be determined that the moisture introduced into (450) has evaporated. For example, if the PU voltage is set to approximately 1.5 V and the resistance sensing voltage measures above approximately 1 V, the resistance value for the moisture sensing terminal (e.g., GND(B1) terminal or GND(B12) terminal) is approximately 6 It could be more than Mohm. According to one embodiment, as the resistance value standard for determining whether moisture flows in increases, the ping-pong phenomenon may be reduced.

According to various embodiments, the processor 410 may control the power supply module 420 to variably set the PU voltage from about 3V to about 1.5V. For example, the processor 410 may set the PU voltage low from about 3V to about 1.5V in response to a moisture detection condition, and after moisture is detected, in response to a dry detection condition, the processor 410 may set the PU voltage from about 1.5V. It can be set as high as about 3V. According to one embodiment, changing the setting of the PU voltage in response to a moisture detection condition or a dryness detection condition may be a hysteresis condition. The processor 410 can change the setting of the PU voltage by lowering it while moisture is flowing in, and can prevent corrosion of the moisture detection terminal.

According to various embodiments, the processor 410 may measure a resistance detection voltage corresponding to the applied PU voltage, and determine whether moisture flows into the connector 450 based on the measured resistance detection voltage. You can. When moisture enters the connector 450, the processor 410 controls the connector control circuit 440 to connect to at least one terminal (e.g., VBUS, CC pin, USB) included in the connector 450. The power can be cut off.

Referring to FIG. 5, in operation 501, a processor (e.g., processor 410 of FIG. 4) of an electronic device (e.g., electronic device 400 of FIG. 4) operates a power supply module (e.g., power supply module of FIG. 4). 420)) can be used to set the PU voltage to about 3V, and the moisture detection module 411 can be used to monitor the resistance detection voltage corresponding to at least one of the GND (B1) terminal or the GND (B12) terminal. there is. According to one embodiment, the processor 410 may monitor the resistance detection voltage for the moisture detection terminal (GND(B1) terminal or GND(B12) terminal) at set time intervals or in real time. The resistance detection voltage may include a voltage value corresponding to at least one terminal (e.g., GND (B12), or GND (B1)) included in a connector (e.g., connector 450 in FIG. 4, or TYPE C connector). You can. For example, when connector 450 operates normally, without moisture entering connector 450, the moisture detection module (e.g., moisture detection module 411 in FIG. 4) responds to the PU voltage set to approximately 3V. Therefore, the resistance detection voltage can be measured at about 3V. When moisture flows into the connector 450, resistance may be generated due to the introduced moisture, and the moisture detection module 411 may measure a resistance detection voltage of less than about 1V in response to the PU voltage set to about 3V. . According to one embodiment, when the resistance detection voltage is measured to be less than about 1V, the processor 410 may determine that moisture has entered the connector 450.

In operation 503, with the PU voltage set to about 3V, the processor 410 determines whether the resistance detection voltage corresponding to the moisture detection terminal (e.g., the GND(B1) terminal, or the GND(B12) terminal) is less than about 1V. You can judge. If the resistance detection voltage is not measured to be less than about 1V, the processor 410 may return to operation 501 and monitor the resistance detection voltage corresponding to the moisture detection terminal. According to one embodiment, if the resistance detection voltage is measured to be less than about 1V, it may mean that moisture has entered the connector 450.

According to one embodiment, the processor 410 can prevent corrosion caused by moisture inflow by cutting off the power supply in response to the at least one terminal. If moisture enters the connector 450, the processor 410 can control the power supply module 420 to change the PU voltage from about 3V to about 1.5.

According to one embodiment, if the resistance detection voltage exceeds about 1V while the PU voltage is set to about 1.5V, it may mean that moisture has evaporated in the connector 450 (e.g., a DRY state). For example, when moisture introduced into the connector 450 evaporates, the resistance component for the moisture detection terminal (e.g., GND (B12) or GND (B1)) may decrease or disappear, and the set PU voltage (about 1.5 A resistive sense voltage close to V) can be measured. According to various embodiments, the processor 410 may determine that moisture has evaporated from the connector 450 when the resistance detection voltage is measured to exceed about 1V while the PU voltage is set to about 1.5V.

If the resistance detection voltage exceeds about 1V in operation 509, in operation 511 the processor 410 connects at least one terminal included in the connector 450 (e.g., at least one terminal to which power is supplied, a VBUS terminal, and a CC terminal). ) can be allowed to supply power. According to one embodiment, since the moisture has evaporated from the connector 450, the processor 410 may control the connector control circuit 440 to allow power supply to the at least one terminal.

According to one embodiment, the time to determine whether the resistance detection voltage exceeds about 1V (e.g., the time to determine whether moisture has evaporated from the connector 450) may be the time when the display 160 is turned on. . For example, to determine whether moisture has evaporated, the processor 410 may apply a current of tens to hundreds of μA to a moisture detection terminal (e.g., the GND (B1) terminal or the GND (B12) terminal). . When the resistance detection voltage is frequently measured, the probability of corrosion of the connector 450 may increase due to moisture flowing into the connector 450. According to one embodiment, when a user uses the connector 450 of the electronic device 400 (e.g., connecting a charger or connecting a peripheral device), the display 160 may be turned on, and the display 160 may be turned on. ) is turned on, it is possible to determine whether moisture flows into the connector 450.
