Description
Technical field:
The utility model relates to technical field of integrated circuits, and LD02 is the integrated circuit that a CMOS technology is made, and be used to touch by the multi-mode of key control and export high-power torch series products, exactly be a kind of integrated circuit (LD02).
Background technology:
Integrated circuit is used widely at present, and identical with the utility model or akin product does not also have discovery and report, thus be necessary, so be necessary on safe, practical property and intelligent degree, to further investigate.
Summary of the invention:
The purpose of this utility model is: the purpose of this utility model is to provide a kind of integrated circuit, and the reliability of its security, degree of intelligence, quality, the feature of environmental protection are improved.
The technical scheme that its technical problem that solves the utility model adopts is: the encapsulation of employing standard 8 pin dual-in-line plastic packagings; Be connected with the charging detection port; Connect external voltage detecting circuit and input are set; The output mode pin order of connection be half bright, entirely bright, flash of light and half bright, entirely bright, close; The PWM output is subjected to button control sequence to change output content, and built-in oscillator and button disappear and tremble, and presses and switches when unclamping.
Specifically describe as follows:
LINJI02 is the integrated circuit that a CMOS technology is made, and is used to touch by the multi-mode of key control and exports high-power torch series products.
The controlled key control of PWM output changes output content in proper order, and built-in oscillator and the button dither functions that disappears is pressed and switched when unclamping.
The output mode pin meets GND or VCC selects output to be in proper order: half bright-bright entirely-flash of light-pass or half bright-bright entirely-pass.
Built-in low-voltage detection circuit, setting voltage can provide external voltage detecting port by external resistance adjustment, and integrated circuit does not have output when guaranteeing charging.
Operating voltage range 3-8V, static standby current is less than 2 microamperes.
Standard 8 pin biserials are inserted plastic packaging (DIP8) encapsulation, meet the lead-free product requirement.
Pin definitions:
Pin 1 power cathode GND
Pin 2 outer meeting resistances are adjusted and are detected voltage
Pin 3 external capacitors
Pin 4 button inputs, the built-in shake that disappears
Pin 6 chargings detect input
The anodal VCC of pin 7 circuit powers
Pin 8 PWM outputs
During output [half is bright], the about 400Hz of frequency
During output [bright entirely], be high level
During output [flicker], the about 1.6Hz of frequency
Prevent battery discharge:
2 pin are that voltage detecting is adjusted pin, set by outer meeting resistance and turn-off output, and are external when be 750K, when supply voltage drops to the internal circuit action shutoff of 4.3 ± 0.2V left and right sides.The outer meeting resistance resistance is big more, and the shutoff voltage value is high more.
3 pin capacitor C values, 0.1 ~ 1 microfarad.
8 pin during supply voltage 6V, can be exported the electric current more than 80 milliamperes to 33 ohm of the minimum values of the base resistance of D882, and bigger if desired drive current can only increase the triode amplification or change D882 into the VMOS pipe.
5 pin can not be unsettled, and also unsuitable powering state switches.
6 pin to the resistance value principle of charging input CH are: during charging, 6 pin current potentials are than the lower slightly 0.5 ~ 1V of 7 pin (Vcc).
Export for preventing during charging:
The charging signals detection port is set separately, can makes this function preferentially the highest, during charging, button is invalid, avoids of short duration rush of current.
Button switching state function:
When system under non-charging and non-under-voltage normal condition, the back system that powers on is the turning off standby pattern of lower power consumption: when the button of circuit 4 pin is pressed over the ground, OP end N pipe is opened, and 2 pin output high level is provided with the resetting voltage point by outer meeting resistance, the oscillator of circuit is started working, frequency divider operation, the button time reach the frequency divider setting go be effective button after the time of trembling, this moment, the rising edge of button changed counter, after combination control, 8 pin output transform states.
Being switched by 5 pin selection keys is four-mode or three-mode.
Four step modes-5 pin meets GND
Electrification reset 8 pin output low levels
Button once, 8 pin output 400HZ left and right sides Ping Bo (half is bright)
Press once 8 pin output high level (bright entirely) again
Press once 8 pin output about 1.6HZ square wave (flicker) again
By once, reset again.
Three step modes-5 pin meets VCC
Electrification reset 8 pin output low levels
Button once, 8 pin output 400HZ left and right sides Ping Bo (half is bright)
Press once 8 pin output high level (bright entirely) again
By once, reset again.
The beneficial effect that the utility model produced: the purpose of this utility model is to provide a kind of integrated circuit, and the reliability of its security, degree of intelligence, quality, the feature of environmental protection are improved.
Description of drawings:
Fig. 1 Fig. 2 is wherein a kind of structure diagram of form of the utility model.
Fig. 3 is the utility model IC interior block diagram
The specific embodiment:
Further describe below in conjunction with drawings and Examples:
Preventing that battery from crossing puts:
When 8 pin had output, 2 pin output high level was provided with the resetting voltage point by outer meeting resistance, and when voltage was reduced to the electrical voltage point of setting, circuit reset was put in case battery is crossed.
For preventing that voltage pulsation from causing the instability of circuit, 3 pin need connect the electric capacity of a 4.7UF to GND.
Prevent output during charging:
The charging signals detection port is set separately, can makes this function priority the highest.During charging, button is invalid, avoids of short duration rush of current.
Button switching state function:
When system under non-charging and non-under-voltage normal condition, power on the back system be the turning off standby pattern of low-power consumption; When the button of circuit 4 pin is pressed over the ground, OP end N pipe is opened, 2 pin output high level, by outer meeting resistance the resetting voltage point is set, the oscillator of circuit is started working, frequency divider operation, the button time reach the frequency divider setting go be effective button after the time of trembling, this moment, the rising edge of button changed counter, after combination control, and 8 pin output transform states.
Being switched by 5 pin selection keys is four-mode or three-mode.
