Pin description:

1 VIN : Charge port positive input +

2 GND : Charger Negative Input -

3 BAT : Lithium Battery +

4 GND : Lithium Battery -

5 GND : Output negative output -

6 VOUT: Output Positive Output +

7 KEY : Output Enable Trigger Port (Low Pulse Trigger)

1 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.

2 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.

3 Allow discharge while charging (Note: Output voltage >4.7/<5V at this time)

 

Applications:

Car charging retrofit

Driving recorder power supply

Mobile power

Portable devices such as mobile phones and tablets

 

Package:

2A 5V Lithium battery charging protection module
