The device provides embedded protective functions. Integrated protection functions are designed to prevent the
destruction of the IC from fault conditions described in the datasheet. Fault conditions are considered as “outside”
normal operating range. Protection functions are designed neither for continuous nor for repetitive operation.

5.3.1
In case of loss of module or device ground, where the load remains connected to ground, the device protects itself
by automatically turning OFF (when it was previously ON) or remains OFF, regardless of the voltage applied on
IN pin. It is recommended to use input resistors between the microcontroller and the BTS50015-1TAA to ensure
switching OFF of channel. In case of loss of module or device ground, a current (I
