TP4057 Description
UMW R TP4057 500mA linear lithium ion battery charger .
TP4057 is an excellent linear charger with constant current and constant voltage for single lithium ion battery.
TP4057 Features
* battery temperature monitoring, undervoltage locking, automatic recharging and two status pins to show charging and charging termination. Features
I Programmable charging current 500mA I No need for external MOSFET, resistance detection and isolation diode I Complete linear charger with SOT23-6 pa
TP4057 Applications
* the thermal feedback can adjust the charging current to reduce the chip temperature. The charging voltage is fixed at 4.24 V, while the charging current can be set externally through a resistor. When the charging current drops to 1 / 10 of the set value after reaching the final floating charge voltag
