  • RE: RM57L843: Generating voltage references

    Hi Edgar, The TPS65381A-Q1 is normally the companion PMIC used with the TMS570/Hercules MCUs. There is an option for the devices with higher core current requirements to use a DCDC for the core rail rather than the LDO controllers. That approach and…

  • RE: ADS1261: Input protect

    Hi Kai, The red point is the input voltage to the customer's system. The first resistor and TVS diode are optional, but in general I would recommend trying to shunt any overvoltage or EMI signal to earth/chasis ground before entering the system as this…

  • RE: [FAQ] TPS65381A-Q1: Can the VDD1_SENSE pin be used to monitor another regulator output if VDD1 LDO controller isn't used in the application?

    Resolved
    Yes, the VDD1 LDO controller of the TPS65381A-Q1 may be re-purposed and used as a voltage monitor for different regulator that is not integrated into the TPS65381A-Q1 if the VDD1 LDO controller isn't used in the application. The VDD1_SENSE pin may…
