Pin description:
1 VIN : Charging port +
2 GND : Charging port -
3 BAT : Battery port +
4 GND : Battery port -
5 GND : Output port -
6 VOUT: Output port +
7 KEY : Output trigger port(Low pulse trigger)
1 In discharge mode(In the charging mode,the KEY function is invalid),
the KEY Trigger once,turn on the output;Continuous trigger twice: turn off the output.
2 When the load access, it will automatically turn on the output.
But if the load is less than 50MA, the output will be turned off after 30 seconds
3 While charging, while discharge, it is allowed
NOTE:
If the output load current is less than 50MA, turn off the output after 30 seconds.
If the output load current is greater than 50MA,continuous turn on the output
