Description
The AT73C201 is a low cost, high performance, fully integrated Battery and Power
Management System for Wireless Cellular Terminals.
The AT73C201 integrates all the regulated power supplies needed to power a terminal
chipset from a Lithium-Ion or Ni-Mh battery pack to Baseband ICs and Memories,
Radio Transceiver, Analog, VCXO, LNA and PA bias and Sim Card in the case of
GSM.
Auxiliary low Ron power supply PMOS switches are available from either the battery
pack or internal regulated power supplies, providing optimum power management by
turning on or off different elements of a handset. The AT73C201 also includes a vibra-
tor motor driver, a set of LED drivers, a smart reset circuit, and a Battery Charger
Switch Driver with built-in state machine for safe boot and pre-charge operation.
In addition, a set of 3 Audio Programmable Gain Amplifiers are provided for handsfree
(on 8
Loudspeaker), Earpiece and Car Kit easy interfacing.
The functions are supervised by a set of voltage monitors, timers and a temperature
shutdown circuit connected to the internal state machine.
Voltages and on-chip temperatures are also visible from an external pin through a mul-
tiplexer for proper connection to the external Baseband ADC.
The AT73C201 is available in a 9x9mm outline, 10x10 ball matrix BGA for optimum
size and performance combination. Its very low standby power dissipation and its high
noise and PSRR performances make the AT73C201 ideally suitable for recent appli-
cations on 2.5G and 3G terminals.
