General Description
The G5880 series are a standalone linear Li-Ion bat-
tery charger with a complete precharge, constant cur-
rent, and constant voltage charge loop. The G5880
series offer integrated two power source, USB-port
and ac-adapter with autonomous power source selec-
tion, power MOSFET, charge status, high accuracy
current and voltage regulation, and charge termina-
tion.
In the USB configuration, 100mA or 500mA of charge
rates could be selected by ISET2. In the ac-adapter
configuration, charge current can be set by an external
resistance.
The charge voltage is regulated at 4.2V, and G5880
series charge cycle would be terminated automatically
based on minimum current after the final regulation
voltage is reached. An internal charge timer provides a
backup safety for charge termination. Other features
include undervoltage lockout, overvoltage lockout,
over temperature protection and auto-recharge if the
battery voltage falls below an internal threshold.
