The internal logic permanently monitors the junction temperature of the output stage. In the event of an over
temperature (
switch off remains latched until the fault is acknowledged and reset by a falling edge at the DEN pin. See also

The BTS50070-1EGA provides Infineon
latched switch off in PWM applications. To reset a latched protective switch off the fault has to be acknowledged
by a falling edge at the DEN pin. For a reset signal it’s recommended to set the DEN signal to HIGH for 20µs before
setting DEN to LOW for 20µs.
