Controller for Power Supply and Battery Management
Rev. 2.2 — 9 April 2004
Preliminary Specification
1. General description
The PCF50606 and PCF50605 are highly integrated solutions for power supply
generation, battery management, and dedicated mobile system functions. A built-in
step down DC/DC converter provides a highly power efficient supply for a digital core,
while 2 additional DC/DC converters and 5 low dropout regulators are available to
supply all other functions in mobile systems. Furthermore, the PCF50606 provides a
10-bit ADC and touch screen readout support. Both devices enables a very efficient
system deep sleep state since it incorporates a real time clock and several wake up
functions. They can be controlled by a host controller via an I2C serial interface and
several dedicated pins. An intelligent interrupt system signals the host controller
about many power management events.
Whenever PCF50606 is mentioned in this document, this refers to both PCF50605
and PCF50606, unless a difference is noted. This document describes bondout
versions A and B; a separate specification is available of bondout version E.
! Next to this specification document, several application notes exist which describe
application advices and known limitations. It is strongly recommended to read these
documents before starting design activities.

2. Featuresc
s The PCF50606 operates from a 1 cell Li-Ion/Li-Polymer or a 3 cell NiCd/NiMH
battery pack.
s A serial interface (I2C) provides the exchange of information for the control data
and status between the PCF50606 and the host controller.
s Low power 32786Hz Xtal oscillator.
s Internal current controlled oscillator that generates the internal system clock.
s Interrupt controller that generates the interrupt request for the host controller. All
interrupt sources can be masked.
s A 8s watchdog timer (hereafter WDT), which shuts down the PCF50606 when it
expires after it is activated once. This watchdog can be reset through the I2C
interface.
s A fully integrated 500mA step-down converter (hereafter DCD) with
programmable output voltages, mask programmable reset voltage and operation
mode. This DC/DC converter generates typically the host controller core supply
voltage or is used as pre-regulator for sub 2V regulators to improve the power
efficiency of such a configuration.
