L6353
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.
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 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).
