TP4056 1A Li-Ion Battery Charger

Overview:

TP4056 is a single-cell lithium-ion battery constant current/constant voltage linear charger. It uses an ESOP-8L package with a heat sink at the bottom and a simple external application circuit. It is very suitable for portable device applications and suitable for USB power supply and adapter power supply. It uses an internal anti-reverse charging circuit and does not require an external isolation diode. Thermal feedback can automatically adjust the charging current to limit the chip temperature under high power operation or high ambient temperature conditions.

The TP4056 charging cut-off voltage is 4.2V, and the charging current can be set by an external resistor. When the charging current drops to 1/10 of the set value, the TP4056 will automatically end the charging process. When the input voltage is removed, the TP4056 automatically enters an ultra-low power standby state, reducing the standby current to less than 1uA. The TP4056 can also be placed in shutdown mode when there is input power, thereby reducing the operating current to 40uA.
