FIG. 11 shows an embodiment of the position sensor 170 shown in FIG.

Referring to FIG. 11, the first position sensor 170 may include a Hall sensor 61, and a driver 62.

For example, the hall sensor 61 may be made of a silicon-based material, and the output VH of the hall sensor 61 may increase as the ambient temperature increases. For example, the ambient temperature may be the temperature of the lens driver, for example, the temperature of the circuit board 190, the temperature of the hall sensor 61, or the temperature of the driver 62.

In another embodiment, the Hall sensor 61 may be made of GaAs, and the output VH of the Hall sensor 61 may have a slope of about -0.06% / ° C.

The first position sensor 170 may further include a temperature sensing element 63 capable of sensing an ambient temperature. The temperature sensing element 63 can output the temperature sensing signal Ts to the driver 62 according to the result of measuring the temperature around the first position sensor 170. [

The driver 62 can output the driving signal dV for driving the Hall sensor 61 and the driving signal Id1 for driving the coil 120. [

For example, the driver 62 receives the clock signal SCL, the data signal SDA, the power supply signals VCC and GND from the control units 830 and 780 using data communication using protocol, for example, I2C communication, Lt; / RTI >

The driver 62 generates a drive signal dV for driving the hall sensor 61 and a drive signal Id1 for driving the coil 120 using the clock signal SCL and the power supply signals VCC and GND, Can be generated.

The first position sensor 170 includes first to fourth terminals for transmitting and receiving the clock signal SCL, the data signal SDA and the power supply signals VCC and GND and a second terminal for supplying a driving signal to the coil 120. [ Fifth, and sixth terminals.

The driver 62 also receives the temperature sensing signal Ts measured by the temperature sensing element 63 and transmits the temperature sensing signal Ts to the controller 62 through data communication using protocol, (830, 780).

The control units 830 and 780 can perform temperature compensation on the output VH of the hall sensor 61 based on the ambient temperature change measured by the temperature sensing element 63 of the first position sensor 170 .

For example, when the drive signal dV of the hall sensor 61 or the bias signal is 1 [mA], the output VH of the Hall sensor 61 of the first position sensor 170 is -20 [mV] +20 [mV].

In the case of temperature compensation for the output VH of the hall sensor 61 having a negative slope with respect to the ambient temperature change, the output VH of the Hall sensor 61 of the first position sensor 170 is 0 [ mV] to +30 [mV].

The output range of the hall sensor 61 of the first position sensor 170 is set to the first quadrant (for example, 0 [mV]) when the output of the hall sensor 61 of the first position sensor 170 is displayed in the xy coordinate system. ~ +30 [mV]) is as follows.

The output of the hall sensor 61 in the first quadrant of the xy coordinate system and the output of the hall sensor 61 in the third quadrant are moved in opposite directions to each other in accordance with the ambient temperature change, The accuracy and reliability of the hall sensor may deteriorate when the driving control section is used. Therefore, in order to accurately compensate for the change in the ambient temperature, a certain range of the first quadrant can be set as the output range of the Hall sensor 61 of the first position sensor 170.

The first position sensor 170 includes first to third terminals for a clock signal SCL and two power supply signals VCC and GND, a fourth terminal for data SDA, And fifth and sixth terminals for providing a driving signal.
