Overview
TP4056 is a single-cell lithium-ion battery constant current/constant voltage linear charger. It adopts a SOP8 package with a heat sink at the bottom and a simple external application circuit. It is very suitable for portable equipment applications. It is suitable for USB power supply and adapter power supply. Inverted circuit, no external blocking diode is required. Thermal feedback automatically adjusts the charge current to limit the die temperature during high power operation or high ambient temperature conditions.
The TP4056 charge cut-off voltage is 4.2V, and the charge 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 1μA. The TP4056 can also be put into shutdown mode when input power is present, reducing the operating current to 40μA.
