For diagnosis purpose, the BTS5020-1EKA provides a combination of digital and analog signals at pin IS. These
signals are called SENSE. In case the diagnostic is disabled via DEN, pin IS becomes high impedance. In case
DEN is activated, the SENSE of the channel is enabled.

The BTS5020-1EKA provides a SENSE current written
circuit to GND / current limitation / overtemperature / excessive dynamic temperature increase or open load at
OFF) a proportional signal to the load current (ratio
