6.3 Power Up Sequence
The ZL30101 requires that the 3.3 V rail is not powered-up later than the 1.8 V rail. This is to prevent the risk of
latch-up due to the presence of parasitic diodes in the IO pads.
Two options are given:
1. Power up the 3.3 V rail fully first, then power up the 1.8 V rail
2. Power up the 3.3 V rail and 1.8 V rail simultaneously, ensuring that the 3.3 V rail voltage is never lower than the
1.8 V rail voltage minus a few hundred millivolts (e.g., by using a schottky diode or controlled slew rate)
