DESCRIPTION
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.
This device is supplied with a Pb-free lead finish (second-level interconnect).
