  • TPS22953: TPS22953 reverse current blocking

    Resolved
    Part Number: TPS22953 Dear TI Support Team, Consider the following scenario: IN = 0V BIAS = 5V EN = 5V OUT = 0.7V SNS = 0.223V (0.7V divided through a voltage divider from OUT) SNS threshold is set to 1.62V through a voltage divider. Is the 0.7V from…

    Great, thank you!

  • TPS22953: What if Vin and GND are reversed?

    TI Thinks Resolved
    Part Number: TPS22953 Tool/software: Dear TI experts, My customer is looking for the parts for the situation of Vin and GND are reversed. The product is powered on by battery and it is changeable by user. So My customer is worried about for connecting…

  • TPS22953: TPS22953 EN pin leakage current is high leading to shutdown with large (100k+) resistor divider values

    TI Thinks Resolved
    Part Number: TPS22953 I am using TI part TPS22953DQCR. The EN pin is supposed to have <0.1uA of leakage current. I thought that meant I could safely use a 357k (high side) and 100k (low side) resistor divider network on the EN pin. I learned that those…

  • TPS22953-Q1: Leakage current at VOUT when disabled

    TI Thinks Resolved
    Part Number: TPS22953-Q1 Tool/software: Hi If the device is disabled, but a voltage is present at the VOUT, what is the expected leakage at the VOUT pin (preferrably over PVT)? Bias voltage is 5.3V. Thanks Jon Eirik
