11 Items


Li-Ion battery charge controller TP4056 (TC4056A) is used in autonomous linear chargers for lithium-ion and lithium-polymer batteries, with an adjustable charge current up to 1 A with thermal protection in an SOP 8 case. Maximum charge current - 1A, charge voltage - 4.2V, there is an input for connecting a battery overheating sensor.

TP4056 is a complete linear charger for one cell of lithium-ion battery. Its SOP structure and few external components make the TP4056 ideal for portable devices. In addition, TP4056 can work in USB adapters.

The charge current in the circuit is set to 1000 mA and can be adjusted by selecting the current-supplying resistor R4, R8 according to the following table:
