Description
Charge Discharge Integrated Module 5V 2A
2A 5V Charge Discharge Integrated Module 3.7V 4.2V for 18650 Lithium Battery Charging Boost Mobile Power Protection
Trigger mode: low level trigger (ground)
MCU users, if you accept a small load KEY can be connected to the microcontroller about 20S to give a low level allows the module to continue working!

Pin description:
. VIN : Charge port positive input +
. GND : Charger Negative Input –
. BAT : Lithium Battery +
. GND : Lithium Battery –
. GND : Output negative output –
. VOUT: Output Positive Output +
. KEY : Output Enable Trigger Port (Low Pulse Trigger)
. In the discharging mode (the charging mode KEY function is invalid), the KEY port is triggered once and the output is turned on; the KEY port is triggered twice in succession and the output is turned off.
. The first time you access the load, the output is automatically turned on. If the load is less than 50MA, the output will be turned off after 30 seconds; if the load is greater than 50MA, the output will be continuously turned on.
. Allow discharge while charging (Note: Output voltage >4.7/<5V>
