All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to V
unless otherwise specified.
Gate pulldown current after the current limit to GATE low (t
Minimum duration of GATE pulldown following a circuit breaker fault. The MAX5921_ automatically restarts after a circuit
breaker fault. The MAX5939_ is latched off and can be reset by toggling UV low. The GATE pulldown does not release until
