Push-pull
Open drain(1)
PB must be held low until the
PSHOLD(2) confirmation

Push-pull
Open drain(1)
PB can be released before the
PSHOLD(2) confirmation
1. External pull-up resistor needs to be connected to open drain outputs.
2. For a successful startup, the PSHOLD (power supply hold) needs to be pulled high within specific time, tON_BLANK.
