Description
The AT73C202 is a low-cost, ultra low-power, power and battery management IC
designed to interface directly with state-of-the-art cellular phones, for example with
2.5G GSM phones. It includes all required power supplies tailored to be fully compati-
ble with the sub-systems of recent mobile phone chipsets, including the RF, analog
and digital (DSP, microcontroller, memories) sections.
The AT73C202 integrates a step-down DC-DC converter that supplies 300 mA with
internal switches and two levels of voltage programming for the baseband core (1.8V
and 2.5V). A low-power mode is available in order to minimize standby current con-
sumption during the “quiet” transmission periods.
In addition, the AT73C202 includes a lowcost battery charger, using a simple external
PNP transistor for Li-Ion or Li-Polymer batteries. Battery operating conditions are
maintained within safe limits under hardware control during the start-up procedure
(when the phone is turned on or a charger is plugged in). The battery pre-charge is
also integrated and self-operated by the AT73C202. On completion the fast charge
and end-of-charge procedure is transferred to the baseband software.
The AT73C202 integrates 7 low-dropout linear regulators specifically designed to sup-
ply RF (x2), analog, memories, etc. It also includes a back-up battery charger and an
ultra low-power regulator dedicated to the baseband real-time clock (RTC) supply dur-
ing sleep mode.
The hardwired start-up mechanism (power management controller state machine)
ensures safe telephone operation during the wake-up and shut-down procedures, and
during the multiple real-life operating conditions of a mobile phone (such charger plug-
in, plug-out, battery plug-in, plug-out, low or dead battery, etc.).
The AT73C202 is packaged into a 49 ball (7x7 matrix), 0.65mm pitch, 5mm x 5mm
outline FBGA package.
