For diagnosis purpose, the BTS5012-1EKB 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 sensed current of the channel is enabled.
7.1
The BTS5012-1EKB 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
mechanism is described on
current. Due to the ESD protection, in connection to
devices if these devices are using another battery feed. The consequence is that the unsupplied device would be
fed via the IS pin of the supplied device.
