Specification
Brand : WSDMAVIS
BulletPoint1 : Shape about 12mm * 12mm, operating voltage 2v-5v,timing can be set to a minimum to a maximum of 2 seconds 1,000 hours.
BulletPoint2 : The circuit is connected as required and the time resistance and power supply voltage are set;Before the power not trigger output is high;Trigger terminal "falling" trigger effective immediately after the trigger output terminal goes low at the same time start the timer circuit.
BulletPoint3 : Set the timer time to recover after the output terminal is high, wait for the next "falling" trigger;The chip is not repeated triggered, meaning that continue to trigger in the period after the trigger chip output low if the trigger is invalid.
BulletPoint4 : The trigger end of "falling" Trigger refers to the instantaneous change from high level to a low level; General refers to VCC high voltage, low means 0-0.3v or GND,provided that they meet the level requirements can be.
BulletPoint5 : Trigger terminal can be connected to touch switch or microcontroller IO port or other digital circuits have a "falling" can effectively trigger;The trigger can be designed to power, only to trigger a short circuit to ground, power is triggered,the time to recover after the output to a high level, waiting for the next Falling edge trigger again.

ProductDescription : Chip features:
1. Using CMOS technology, low power consumption, lead-free and environmentally friendly.
2. Output low level can directly push LED (please add current limiting resistor), output high level can push transistor (please add current limiting resistor).
3. Resistor can be used to adjust the timing time. There are 8*N (N=0.1.2.3) times timing options, and the time can be adjusted from 2s-1000h.
4. You can choose trigger timing and trigger terminal grounding power-on timing.
5. Standby output high level, falling edge trigger, output low level after triggering, and return to high level after the delay is over.

Pin description:
The following figure counts from bottom to top: PIN1=power negative, PIN2=trigger, PIN3=output, PIN4=power positive
The P1 short circuit (short circuit of two small pads) in the figure below is the timing time equal to the time in the resistance meter multiplied by 8 times
The P2 short-circuit (short-circuit of two small pads) in the figure below is equal to the time in the resistance meter multiplied by 64 times
In the figure below, P1 and P2 are short-circuited at the same time (two small pads are short-circuited). The timing time is equal to the time in the resistance meter multiplied by 512 times
