Regarding application of TPS65381, I have several questions and hope to get support from your side:
- How to use NRES? Can it be connected directly to MCU? Is there pull-up resistor needed?
- As we understand, DIAG_OUT is output of diagnostic signals selected by SPI, is it right? If choosing analog signal as output, how to select low-pass resistor and capacitor, what frequency need to filter out?
- Is RSTEXT used to set delay time of NRES by adjusting resistance? How to select the resistor?
- If we decide not to use CAN wake up function, how to configure CANWU pin (floating or pull down)?
- If we choose 5V as sensor supply voltage, should VSIN be connected to VDD6? Should VTRACK be connected to VDD5? How to choose the resistor for VSOUT1 when we want unity gain feedback?
- If we want VDD1 to be 1.2V, how to choose resistor for VDD1_SENCE? How to calculate it?
