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).
