All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to V
unless otherwise specified.
Current into V
Minimum duration of GATE pulldown following a circuit-breaker fault. The circuit breaker can be reset during this time by
toggling UV low, but the GATE pulldown does not release until t
Limits are 100% tested at T
