Pin description:
VIN: Charging port
GND: Charging port -
BAT: Battery port
GND: Battery port -
GND: Output port -
VOUT: Output port
KEY: Output trigger port(Low pulse trigger)
How to use:
1. In discharge mode(In the charging mode, the KEY function is invalid), trigger the KEY once - turn on the output; Continuously trigger KEY twice - turn off the output.
2. When connecting the load for the first time, it will automatically turn on the output. If the load is less than 50mA, the output will be turned off after 30 seconds; If the load is more than 50mA, it will continuously turn on the output.
