The TLE8386EL has integrated circuits to diagnose and protect against output overvoltage, open load, open
feedback and overtemperature faults. In case any of the four fault conditions occur the Status output ST will output
an active logic low signal to communicate that a fault has occurred. During an overvoltage or open load condition
the gate driver outputs SWO will turn off. Figure 11 illustrates the various open load and open feedback conditions.
In the event of an overtemperature condition the integrated thermal shutdown function turns off the gate drivers
and internal linear voltage regulator. The typical junction shutdown temperature is 175°C. After cooling down the
IC will automatically restart operation. Thermal shutdown is an integrated protection function designed to prevent
immediate IC destruction and is not intended for continuous use in normal operation.
