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.
