Allows active control of external N-Channel FET gate to perform ORing
function.
Chip bias input. Also provides a sensing node for external FET control.
Low side of floating high voltage reference for all of the HV chip circuitry.
Chip ground reference point.
Provides an open drain active low output as an indication that a fault has
occurred: GATE is OFF (GATE <
