Functional Description
4.1.3
Power Control System
The power control system on MC13783 interfaces with the processors via different IO signals and the SPI
bus. It also uses on-chip signals and detector outputs. It supports a system with different operating modes
as described below.

Description
Only the MC13783 core circuitry at VATLAS and the RTC module are powered. To exit the Off mode requires
a turn on event.
The switchers and regulators are powered up sequentially to limit the inrush current. At the end of the start-up
phase, the RESETB and RESETBMCU will be made high and the circuit transitions to On.
The circuit is fully powered and under SPI control. To stay in this mode, the WDI pin has to be high and remain
high. If not, the part will transition to Off mode.
All switchers and regulators are powered off except for VBKUP1 and VBKUP2. The RESETB and
RESETBMCU are low. The MC13783 enters Cold Start mode when a turn on event occurs.
All switchers and regulators are powered off except for VBKUP1 and VBKUP2. RESETB is low and
RESETBMCU is kept high. The 32 kHz output signal CLK32KMCU can be maintained in this mode as well.
The MC13783 enters Warm Start mode when a turn on event occurs.
The switchers and regulators are powered up sequentially to limit the inrush current. The reset signals
RESETB is kept low and RESETBMCU is kept high and CLK32KMCU can be kept active. At the end of the
warm start up phase, the RESETB will be made high and the circuit transitions to On.
Defined as a momentary loss of power. This can be caused by battery contact bounce or a user-initiated
battery swap. The memory and the processor core are automatically backed up in that case by the coin cell
depending on the power cut support mode selected. The maximum duration of a power cut as well as the
maximum number of power cuts to be supported are programmable. When exiting the power cut mode due to
reapplication of power the system will start up again on the main battery and revert back to the battery supplied
modes.
Turn On Events If the MC13783 is in Off, User Off or Memory Hold mode, the circuit can be powered on via a turn-on event.
The turn-on events are listed below. To indicate to the processor which turn-on event occurred, an interrupt bit
is associated with each of the turn-on events.
ON1B, ON2B or ON3B pulled low, a power on/off button is connected here.
? CHRGRAW pulled high which is equivalent to plugging in a charger.
? BP crossing the minimum operating threshold which corresponds to attaching a charged battery to the
phone.
? VBUS pulled high which is equivalent to plugging in a supplied USB cable.
? Time of day alarm which allows powering up a phone at a preset time.
The default power up state and sequence of the MC13783 is controlled by the power up mode select pins
PUMS1, PUMS2 and PUMS3. In total three different sequences and five different default voltage setting
combinations are provided. At power up all regulators and switchers are sequentially enabled at equidistant
steps of 2ms to limit the inrush current.
