General Description
The G5800 is a power management system chip opti-
mized for Mobile phone handsets. It contains seven
LDOs, one to power each of the critical Mobile phone
sub-blocks. Sophisticated controls are available for
power-up during battery charging, keypad interface,
and RTC alarm. The G5800 is optimized for maximum
battery life, featuring a ground current of only 108µA
and 187µA when the phone is in standby and opera-
tion respectively.
The G5800 battery charger can be used with lithium
ion (Li+) and nickel metal hydride (NiMH) batteries.
The G5800 contains three open-drain output switches
for LED, alerter and vibrator control. The SIM interface
provides the level shift between SIM card and micro-
processor.
The G5800 is available in 48-pin QFN package. The
operating temperature range is from -25°C to +85°C.
