The devices operate over the -40NC to +85NC extended temperature range. Reverse-Current Blocking The bidirectional FET switch prevents current flowing from either power input to the other when the switch is disabled. EN/EN Input The MAX14634’s switch position is controlled by an EN active-low logic input. The switch is on when EN is logiclow and off when EN is logic-high. EN is internally pulled down to ground by RPD. The MAX14680’s switch position is controlled by an EN active-high logic input. The switch is on when EN is logichigh and off when EN is logic-low. EN is internally pulled down to ground by RPD.
