2 / 11 page DESCRIPTION (continued) It monitors the on-state voltage drop of the driven power device and protects it against overload and short circuit. The on-state voltage drop level is externally pro- grammable from 5 to 15V. This function is inhib- ited during the turn-on of the external power de- vice for an externally programmable period. An internal inhibition time of 200ns avoids false triggering. 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 configu- rations. 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).
