Controller for power supply
and battery management
Preliminary specification
PCF50603
1.3 Battery management
• Operates from a three cell NiCd/NiMH or a one cell
Li-ion battery pack
• Battery Voltage Monitor (BVM) to detect a too low main
battery voltage with programmable threshold levels.
A low battery condition is reported via the interrupt
mechanism.
• Charger control. There is an option between two
different charger control functions, depending on the
configuration:
– Configuration Constant Current Constant Voltage
(CCCV). Linear charger control supporting Li-ion as
well as NiCd/NiMH battery types for a wide range of
battery capacities.
– Configuration BATMAX comparator that compares
the battery voltage against a programmable
threshold voltage. This function can be activated by
software and is used to detect the end-of-charge.
• Supports the use of a backup battery that powers at
empty main battery situations. The backup battery is
used to supply the RTC, the internal state and the
LPVDD supply in it’s ECO mode. Goldcaps, Li and Li-ion
cells are supported.
• Includes a Backup Battery Charger (BBC).
A rechargeable backup battery or backup capacitor can
be charged from the main battery. For charging, a
programmable constant voltage mode is supported.
1.4 Subscriber identity module card interface
• Two different modes that can be selected with the
Subscriber Identity Module card Interface (SIMI):
– Transparent interface including an arbiter and signal
level translators
– Subscriber Identity Module (SIM) card interface with
integrated sequencer, arbiter and signal level
translators. The sequencer supports and controls
card activation and de-activation, warm reset and
controlled clock stop for power-down modes.
• Dedicated SIM supply (SIMREG). Supports
3.0 V and 1.8 V cards, including a power saving ECO
mode for the power-down mode of the SIM card.
• Enhanced ESD protection on all pins that connect to the
SIM card contact pins.
2 APPLICATIONS
• Mobile phones.
3 GENERAL DESCRIPTION
The PCF50603 is a highly integrated solution for power
supply generation, battery management including
charging and a SIM card interface including supply
generation. The device is controlled by a host controller via
a 400 kHz I²C-bus serial interface.
