The module comes with a lithium battery protection function (the lithium battery does not need to have a protection board, it does not matter if it has a protection board)
Over-current protection (OCP)
Overvoltage protection (OVP)
Short Circuit Protection (SCP)
Over-temperature protection (OTP)
Charge and discharge power level 4 interval indication
Pin description:
VIN : Charge port positive input +
GND : Charger Negative Input –
GND : Lithium Battery –
BAT : 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 at this time)Wiring Instructions
When the module is plugged in, the output will switch to external power supply (it will be powered off for 0.3s). When charging, the output voltage will be less than >4.7/<5V, depending on the charger load capacity!
Trigger mode: low level trigger (ground)
Connect to the single-chip microcomputer, if the connection is less than the load KEY, you can connect the single-chip microcomputer for about 20s to give a low level to keep the module working continuously.Before purchase:
