29 / 58 page Data Sheet 29 Rev. 1.00 2017-08-24 BTS7040-2EPA PROFETTM+2 Protection 8 Protection The BTS7040-2EPA is protected against Overtemperature, Overload, Reverse Battery (with ReverSave™) 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 each 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.
