7.3.4
In case of a short circuit between the OUTput-pin and the
impedance) of the load current will flow through the short circuit. As a result, a lower current compared to the
normal operation will flow through the DMOS of the BTS5090-1EJA, which can be recognized at the SENSE
signal. The open load at OFF detection circuitry can also be used to distinguish a short circuit to
an external resistor to ground

7.3.5
An overload condition is defined by a current flowing out of the DMOS reaching the current limitation and / or the
absolute dynamic temperature swing
shutdown temperature
In that case, the SENSE signal given is by
The device has a thermal restart behavior, such that when the overtemperature or the exceed dynamic
temperature condition has disappeared, the DMOS is reactivated if the IN is still at logical level one. If the DEN
pin is activated, the IS pin is not toggling with the restart mechanism and remains to
7.3.6
In the case of inverse current, the channel will indicate open load in OFF state and indicate open load in ON state.
