Sell ??original ICTP4056

TP4056 is a complete single-cell lithium-ion battery with a constant current / constant voltage linear charger. SOP8 / MSOP8 package and low external component count in the bottom finned makes TP4056 ideal for portable applications. TP4056 can fit USB power supply and adapter power. As a result of internal PMOSFET architecture, coupled with anti-down charging road, so no external blocking diode. Thermal feedback can automatically adjust the charge current to high power operation or high ambient temperature conditions to limit the die temperature. Charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. When the charge current drops after the final float voltage setpoint 1/10, TP4056 automatically terminates the charge cycle. When the input voltage (AC adapter or USB supply) is removed, TP4056 automatically enters a low current state, dropping the battery drain current to less than 2uA. TP4056 when there is power supply can also be put into shutdown mode, reducing the supply current is reduced to 55uA. TP4056 Other features include battery temperature detection, undervoltage lockout, automatic recharge and two to indicate charging, the LED status pin end.
