TPS25982: TPS259823LNRGET IC output is not stable

Part Number: TPS25982

Hi All,

We are having a design in which we uses TPS259823LNRGET for hotswap. We calculated the values of components based on the excel sheet.

But when we try to power the ic. we are not getting the expected output, instead the value is varying. Can anyone faced the same issue or is there anything we are missing.

Please find the attache snippet of schematic for your reference.

  • Hi Hareesh,

    The value of resistance on ILIM pin is recommended to be within 100 Ω and 773 Ω. You are using a RILIM of 10 kΩ which sets the current limit to a very low value and this is causing the device not to power up. 

    Use equation below to select RILIM as per your required current limit value.

    Also, connect LDSTRT pin to GND to enable the device
