AURIX™ MCU: IEVRSB exceeds the specifications of the datasheet for AURIX™ TC2xx device – KBA235306
- Check the junction temperature (TJ) is approximately 25°C.
- Another reason can be that the device failed to enter the standby mode. It reports that when the user connects VEVRSB pin alone at 5 V and does not supply the microcontroller, then it immediately consumes approximately 1.5 mA. Therefore, IEVRSB is larger than the specified value if the device fails to enter the standby mode and VEVRSB alone is supplied.
For the detailed procedure to enter standby mode, see the “Power Supply & Power Management Controller (PMC)” section in the User’s manual.
Note: This KBA applies to the following series of AURIX™ MCUs:
- AURIX™ TC2xx series
