CXCH76025 is a standalone linear Li-Ion battery charger with a complete pre-charge, constant-current and constant-voltage charge loop. No external power MOSFET, sense resistor and blocking diode

The CXCH76025 is a standalone linear Li-Ion battery charger with a complete pre-charge, constant-current and constant-voltage charge loop. No external power MOSFET, sense resistor and blocking diode is required due to internal power MOSFET architecture. The charge voltage is regulated at 4.2V, and the charge current is programmable by an external resistor. After the final regulation voltage is reached and the charge current drops to 1/10th the programmed charge current, the open drain NMOS CHRG pin would be turn off automatically without terminating the charge loop. Other features include under voltage lockout, automatic recharge, over temperature protection and a charge status indication pin
