Single Cell Li-Ion Battery Linear Charger

General Description
The G5808 is a complete standalone linear Li-Ion bat-tery 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 up to 2A. After the final regulation voltage is reached and the charge current drops to the pro-grammed end-of-charge current, the open drain NMOS STATUS pin would be turn off automatically and the charge loop would be terminated after timeout.

Other features include under voltage lockout, auto-matic recharge, an NTC thermistor interface for charging the battery in a safe range, over temperature protection and two charge status indication pins.
