Description
The AT73C203 device provides an integrated solution to portable and handheld appli-
cations built around microprocessors requiring “smart” power management functions,
such as PDAs, Palmtop computers, point-of-sales terminals, 3G modems, etc.
Its compact package outline and small size of external components make the
AT73C203 suitable for PCMCIA card power management as well.
The AT73C203 integrates a power switch controller that, when connected to an exter-
nal power switch, may be used for automatically selecting one of four possible power
sources:

Plugtop power supply unit 5V (PSU)
PC Host USB supply
The power switch output (VDD-PSU line) is connected directly to external auxiliary
components such as a radio or any other “current hungry” module.
The AT73C203 is also equipped with four digital rails from VDD-PSU to supply a base-
band chip, a reset generator for the baseband chip, and a SPI interface to control the
AT73C203 via an internal register set. The USIM interface allows the application pro-
cessor to communicate with and control a USIM card. Charge control enables the
application processor to charge the battery from the PSU or USB. A state machine
can also determine whether to charge the internal battery through USB at start-up.
Additionally, hardware monitoring gives information to the application processor when
a voltage drop occurs (programmed via internal registers).
