General Description
The G5803 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 block-ing 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 exter-nal 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, auto-matic recharge, over temperature protection and a charge status indication pin.
