The TLE8386-2EL has integrated circuits to protect against output overvoltage, open feedback and
overtemperature faults. During an overvoltage the gate driver outputs SWO will turn off. In the event of an
overtemperature condition the integrated thermal shutdown function turns off the gate drivers and internal linear
voltage regulator. If the connection from pin FB to the output voltage resistor divider should be lost, an internal
current source connected to Pin FB will draw the voltage above this limit and shut the external MOSFET off. 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.
