TPS65094: Over current protection behavior

Hi Tiger,

The current limit itself does not have undervoltage protection (UVP), however the part has power good monitoring on all rails so if current limit causes voltage to droop, the part will initiate emergency shutdown unless the power fault is masked in the power fault register.

After emergency shutdown, the TPS65094 will check the state of the PMICEN pin. If high, it will begin the start up as normal. There is a 10 ms mask of power fault during power up. If current limit prevents the output from reaching power good target within that 10 ms, the part will emergency shutdown again and repeat until PMICEN is not high.
