2A 5V Charge Discharge Integrated 3.7V 4.2V Lithium Battery Boost Mobile Power Protection Diy Electronic PCB Board Module
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!
4-in-1 Charging / Discharging / Lithium Battery Protection / Battery Level Indicator Module
Charging voltage: DC 4.5V-5.5V (DC 5V recommended)
Charging current : 0-2.1A
Charging quiescent current : 100uA
Full voltage: 4.2V+-1%.
Discharge current: 0-2.4A;
Discharge quiescent current : 50uA
Discharge efficiency: up to 96%
Output voltage: 5V
Output current: 0-2.4A;
Ambient temperature: -20° to +85°
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)
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 at this time)
