TPS5402: Reverse voltage condition

Part Number: TPS5402

Hi,

We got a question from the customer about TPS5402.
Could you help us?

[Question]
- When the power supply is not applied to VIN, the output voltage conducts through the body diode and the less than 1mA current flows to VIN. Please refer to below figure. Are there any concerns on this condition?
- How much is the maximum recommended currnet of the internal body diode?

Best Regards,
tateo

  • Hi Tateo,
    1. if the reverse current less than 1am as you said, the device is safe
    2. There is no accuracy data for this parameter, but, normally, less than 100mA is safe for this device.
