QFN-48 package

The SS8000 is a power-management system chip

optimized for GSM handsets. It contains seven LDOs,

one to power each of the critical GSM sub-blocks.

Sophisticated controls are available for power-up

during battery charging, keypad interface, and RTC alarm.

The SS8000 is optimized for maximum battery life

featuring a ground current of only 107µA in standby and

187µA when the phone is in operation.

The SS8000 battery charger can be used with lithium

ion (Li-Ion) and nickel metal hydride (NiMH) batteries.

The

SS8000

contains

three

open-drain

output

switches for LED, alerter and vibrator control. The SIM

interface provides the level shift between SIM card and

microprocessor.

The SS8000 is available in a 48-pin QFN package. The

operating temperature range is from -25°C to +85°C.
