TCA9517: any risk with the below design?

Part Number: TCA9517

Customer is asking whether the below circuit is ok during standby mode. When P3V3_STBY is on, and EN is enabled. Will there be leakage current go through P3V3_STBY to P1V8_VDD_IO?

  • Hey Aki,

    I don't see a problem with this. I am assuming that when you state this question, you also mean that the P1V8_VDD_IO is off? If so, the device would just be in undervoltage lock out and be high impedance on the I2C buses for our device. You won't accidentally back bias any body diodes.
