Controller for power supply

and battery management

Preliminary specification

PCF50603

1 FEATURES

1.1 System control

• Serial 400 kHz I2C-bus interface to transfer the control

data between the PCF50603 and the host controller

• On/Off Control (OOC) module to control the power

ramp-up and ramp-down sequences for the handset.

Furthermore it determines the supported system

operating states: NOPOWER, SAVE, STANDBY and

ACTIVE to realize minimum power consumption in all

states.

• Internal Current Controlled Oscillator (CCO) generates

the internal high clock frequency. The generated

frequency is typically 3.6 MHz.

• An accurate 32.768 kHz oscillator. This oscillator can be

used to supply the 32 kHz clock domains in the system,

to improve the accuracy of the internal clock and to

reduce the power consumption of the PCF50603.

• Interrupt controller (INT) that generates the interrupt

request for the host controller. All interrupt sources can

be masked.

• The Real Time Clock (RTC) module uses the 32 kHz

clock to provide time reference and alarm functions with

wake up control for the handset

• One accessory recognition pin with debounce filters and

capability to start up the system (REC1_N)

• One accessory detection comparator input pin with

programmable threshold levels that issues an interrupt

when an accessory is connected (REC2_N)

• Two Pulse-Width Modulators (PWM1 and PWM2) which

generate an output voltage with programmable duty

cycle and frequency

• Two LED modulators (LED1 and LED2) capable of

generating eight different blinking patterns with eight

different repetition periods

• Three General Purpose Outputs (GPO) programmable

via the serial interface. The GPOs are open-drain

NMOST outputs, capable of handling the full battery

voltage range and high sink currents. The GPOs can be

programmed to be continuously active LOW or 3-state,

in addition the GPO outputs can be controlled by the

LED or PWM modulators.

• Watchdog timer that can be activated by software.

1.2 Supply voltage generation

• The power supplies have three programmable activity

modes (OFF, ECO and ON). In the ACTIVE state, the

operation modes can be selected by the two external

pins PWREN1 and PWREN2.

• One Charge Pump (CP) with programmable output

voltage for the supply of white or blue LEDs

• Two 100 mA LDO voltage regulators (RF1REG and

RF2REG) with fixed output voltage (mask

programmable) for RF supplies. RF1REG and RF2REG

are optimized for low noise, high power supply rejection

and excellent load regulation.

• Two 150 mA LDO voltage regulators (D1REG and

D2REG) optimized for small external capacitors.

D1REG provides a programmable output voltage,

D2REG provides a fixed output voltage (mask

programmable).

• One 150 mA LDO voltage regulator (IOREG) dedicated

for the supply of the I/O pads. IOREG has a fixed output

voltage (mask programmable) and is optimized for a

small external capacitor.

• One 100 mA LDO voltage regulator (LPREG) with fixed

output voltage (mask programmable). In low power

operation (ECO) mode LPREG can be used to

permanently supply parts in the system in all activity

states.

• One 100 mA LDO voltage regulator (D3REG) with

programmable output voltage. D3REG is optimized for a

small external capacitor.

• One 250 mA LDO voltage regulator (HCREG) with

programmable output voltage. The high current HCREG

is optimized for applications like hands-free audio.

• D1REG, D2REG, D3REG, IOREG and LPREG support

ECO mode. In this mode the output current is limited to

1 mA and the internal power consumption is reduced

significantly.

• The Temperature high Sensor (TS) provides thermal

protection for the whole chip

• Enhanced ESD protection on all pins that connect to the

main battery pack

• Microphone bias voltage generator with low noise and

high power supply rejection (MBGEN).
