Power Management Unit for Mobile Phones
General Description
The AS3653 device is a highly integrated solution for
power supply generation and monitoring, battery
management including charging and SIM card
communication. It is controlled via a serial control interface
and integrates all necessary system specific functions such
as clock, reset and interrupt generation, voltage and
temperature monitoring, accessory detection and On/Off
