Overview
The TP4057 is a constant current/constant voltage charger for single cell Li-Ion batteries. No external sense resistor or blocking diode is required and its SOT package make it ideally suited for portable applications. The TP4057 is designed to work within USB power specifications. An internal block regulates the current when the junction temperature increases, in order to protect the device when it operates in high power or high ambient temperature. The charge voltage is fixed at 4.2V, and the charge current limitation can be programmed using a single resistor connectd between PROG pin and GND. The charge cycle is automatically terminated when the current flowing to the battery is 1/10 of the programmed value. If the external adaptor is removed, the TP4057 turns off and a 2μA current can flow from the battery to the device. The device can be put into Shutdown Mode, reducing the supply current to 30μA. The device also has a charge current monitor, undervoltage lockout, automatic recharge. The device is packaged in SOT-23-6L.
