ACTIVE
(1) Minimum delay time between WAKEUP rising edge and IC rady to accept I 2C transaction .
(2) It takes 2ms minimum for each internal boost regulator to start up before VNEG can be enabled .
(5) It takes up to 2ms for LDOs (VPOS,VNEG) and 1ms for charge pumps (VDDH,VEE), to reach their steady state after being enabled.
DLY 0-DLY 3 are power up /down delays defined in register PWR _SEQ 1 and PWR _SEQ2.
In this example the first power-up sequence is determined by GPIO control (WAKEUP is pulled high while PWRx pins are low).
Power-down and 2nd power-up sequence is controlled by register settings (WAKEUP pin is toggled with at least one PWR pin
held high).

SOFTSTART
Softstart for DCDC1, DCDC2, LDO1, and LDO2 is accomplished by lowering the current limits during start-up. If
DCDC1 or DCDC2 are unable to reach power-good status within 10 ms, the corresponding UV flag is set in the
interrupt registers, the interrupt pin is pulled low, and the device enters STANDBY mode. LDO1, LDO2, positive
and negative charge pumps have a 5ms power-good time-out limit. If either rail is unable to power up within 5 ms
after it has been enabled, the corresponding UV flag is set and the interrupt pin is pulled low. However, the
device will remain in ACTIVE mode in this case.
