5.3.5
In case of reverse polarity, the intrinsic body diode of the power DMOS causes power dissipation. To limit the risk
of overtemperature, the device provides Infineon
limited by turning the DMOS ON. The DMOS resistance is then equal to R
Additonally, the current into the logic has to be limited. The device includes a R
in the diodes. To avoid overcurrent in the R
refer to maximum current described in
the current in the sense transistor which behaves as a diode.

In case of overload, high inrush current or short circuit to ground, the BTS50015-1TAA offers several protection
mechanisms. Any protective switch OFF latches the output. To restart the device, it is necessary to set IN=LOW
