WAKE-UP AND POWER UP SEQUENCING
The TPS65180/TPS65181 and TPS65180B/TPS65181B support flexible power-up sequencing through GPIO
control using the PWR3, 2, 1, 0 pins or I2C control using the PWR_SEQ0, 1, 2 registers. Using GPIO control, the
output rails are enabled/disabled in the order in which the PWRx pins are asserted/de-asserted, respectively, and
the power-up timing is controlled by the host only.
In I2C control mode the power-up/down order and timing are defined by user register settings. The default
settings support the E Ink Vizplex
panel and typically do not need to be charged by the user.
