Diagnosis  
For diagnosis purpose, the BTS7040-1EPA provides a combination of digital and analog signals at pin IS. These  
signals are generically named SENSE and written IIS. In case of disabled diagnostic (DEN pin set to “low”), IS  
pin becomes high impedance.  
A sense resistor RSENSE must be connected between IS pin and module ground if the current sense diagnosis is  
used. RSENSE value has to be higher than 820 Ω (or 400 Ω when a central Reverse Battery protection is present  
on the battery feed) to limit the power losses in the sense circuitry. A typical value is RSENSE = 1.2 kΩ.  
Due to the internal connection between IS pin and VS supply voltage, it is not recommended to connect the IS  
pin to the sense current output of other devices, if they are supplied by a different battery feed.  
See Figure 32 for details as an overview.
