Protection  
The BTS7040-1EPA is protected against Overtemperature, Overload, Reverse Battery (with ReverseON) and  
Overvoltage. Overtemperature and Overload protections are working when the device is not in Sleep mode.  
Overvoltage protection works in all operation modes. Reverse Battery protection works when the GND and VS  
pins are reverse supplied.  
8.1  
Overtemperature Protection  
The device incorporates both an absolute (TJ(ABS)) and a dynamic (TJ(DYN)) temperature protection circuitry for  
the channel. An increase of junction temperature TJ above either one of the two thresholds (TJ(ABS) or TJ(DYN)  
)
switches OFF the overheated channel to prevent destruction. The channel remains switched OFF until  
junction temperature has reached the “Restart” condition described in Table 14. The behavior is shown in  
Figure 22 (absolute Overtemperature Protection) and Figure 23 (dynamic Overtemperature Protection).  
TJ(REF) is the reference temperature used for dynamic temperature protection.
