SEQUENCE
An ON sequence is only permitted when the supply voltage SYSVDD exceeds a programmable threshold V
Section 24.4 for details of SYSVDD voltage monitoring.
Selected OFF events may be masked during Battery Charging using the CHG_OFF_MASK bit. This allows user-initiated OFF
events (Software OFF, ON pin request, GPIO OFF request) to be inhibited. See Section 17.7.2.

EVENT
An ON request occurs if the RTC Alarm occurs
in the OFF power state. See Section 20.
Requires a GPIO to be configured as “Power
On request” or “Power On/Off request”. See
Section 21.
Requires the ON
generate ON request. See Section 11.6.
Writing CHIP_SLP = 0. See Table 2.
Occurs when a Charger Interrupt event is
triggered. See Section 17.7.8.
Requires the Watchdog to be configured to
generate WAKE request. See Section 25.
A WAKE request occurs if the RTC Alarm
occurs in the SLEEP power state. See
Section 20.
Requires a GPIO to be configured as
“Sleep/Wake request”. See Section 21.
Requires the SYSVDD monitor circuit to be
configured to generate WAKE request. See
Section 24.4.
Requires the ON
generate WAKE request. See Section 11.6.
Requires the Watchdog to be configured to
generate Device Reset. See Section 25.
See Section 24.
See Section 24.
Configurable option for each LDO/DC-DC
Converter. See Section 15.
Writing CHIP_ON = 0. See Table 2.
Requires the ON
generate OFF request. See Section 11.6.
See Section 26.
Requires the SYSVDD monitor circuit to be
configured to generate OFF request. See
Section 24.4.
SYSVDD has fallen below the SHUTDOWN
threshold. See Section 24.4.
Requires a GPIO to be configured as “Power
On/Off request”. See Section 21.
(including FLL) have failed to start up within
the permitted time.
Error condition detected in LDO13
Writing CHIP_SLP = 1. See Table 2.
Requires a GPIO to be configured as “Sleep
request” or “Sleep/Wake request”. See
Section 21.
