The device provides embedded protection functions against over temperature, over load and short circuit.
Note: Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
7.1
The device is protected against over temperature resulting due to overload and / or bad cooling conditions.
The BTS3160D has a thermal latch function. The thermal latch is reset by IN-Low signal. See
latch behavior.

The BTS3160D is equipped with a voltage clamp mechanism that keeps the Drain-Source voltage V
level. This stage is also used for inductive clamping.

The condition short circuit is an overload condition of the device. Dependent on the short circuit resistance the
current increase is more or less steep. In condition of high ohmic short the device heats up and the turn off is due
to over temperature. In condition low ohmic short the device turns off on a threshold current level before the over
temperature condition is detected. In order to allow short current spikes, the turn off occurs with the delay time
