Available in both DIP and SO package, it can be triggered with a logic level or with the signal from an optocoupler or a pulse transformer. It filters parasitic input signals and drives any MOS or IGBT.

The on-state voltage drop level is externally programmable from 5 to 15V. This function is inhibited during the turn-on of the external power device for an externally programmable period. An internal inhibition time of 200ns avoids false triggering. PIN CONNECTION (top view) Overload or overheating are signalled on an alarm output. If temperature continues to increase the power output is switched off and maintained in the off-state until the temperature decreases below the low threshold. A programmable turn-on delay avoids cross conduction in bridge configurations. To preserve the external power device (especially IGBT) from the risk of latch-up, the gate voltage can be risen in two different steps (of which the first is externally programmable from 7 to 11V).
