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.
