Soft Turn-Off (STO)
In the event of short circuit, the STO circuit increases the resistance in series with R
speed. This produces smaller voltage spike above the collector emitter of the IGBT by reducing the di/dt value. Because in
short-circuit conditions the IGBT's peak current increases and some stray inductance is always present in power circuits, it
must fall to zero in a longer time than at normal operation. The soft turn-off time can be adjusted by connection an external
resistor R
External Error Input (EEI)
The external error inputs on the secondary side (high potential) of the gate driver can be used for external fault signals from
e. g. an over current protection circuit or over temperature protection circuit to place the gate driver into halt mode.
Disabling of this function can be achieved by no connection or connection to +15V (e. g. SEC_TOP_15P, SEC_BOT_15P to
SEC_TOP_ERR_IN and SEC_BOT_ERR_IN). It is possible to use only one error input.

Please note:
The soft turn-off function is no complete protection from induced over voltage in the event of short-circuit turn-off.
A HIGH signal at PRIM_HALT_IN does not activate a soft turn-off.

Application Hints
The turn-off behaviour and over voltage peaks depends on DC link
voltage, stray inductance of the power circuits, type of IGBT, etc. and
has to be selected according the specific application. Due to this
influence a general value for R
resistor has to be selected according to the behaviour of the specific
circuitry.
The soft turn-off time is limited to 10µs. After this time the output stage
turn-off with used R
Disabling of Soft Turn-Off can be achieved by R
bridge.
