Li-Pol TP4056 charger TP4056 single 1S 3.7V microUSB cell with protections
Simple charger for 1-purpose lithium-polymer batteries with a nominal voltage of 3.7V. Maximum charging current is 1000 mA. The system is powered via the microUSB connector or via wires connected to the IN+ and IN- inputs. The module is protected against excessive discharge below 2.5 V and excessive current consumption above 3 A.
Outputs
The module has 6 solder fields and a micro USB connector.
| PIN | DESCRIPTION |
|---|---|
| IN+ | Supply voltage from 4.5 V to 5.5 V. |
| IN- | The weight of the system. |
| BAT+, BAT- | Connectors for connecting Lipol 3.7 V batteries. |
| OUT+, OUT- | Connections for connection powered. When too low a battery voltage is detected, the system switches the power supply from BAT connectors toIN. |
