Part Number: TPS2595

Tool/software:

Hi Support team

If the output voltage is 5V and the output current is 0.1A, how many volts will be at pin 7(ILM) of TPS259530?

Please also tell me the calculation formula.

Best  regards.

    Hi! 

    ILIM pin in TPS2595 eFuse is a dual function pin which also acts like an IMON pin. Exact voltage will depend on the RILIM used. The device will source some current at this pin with the ratio of ILIM/IOUT = GIMON. This is typically 276 uA/A. 

    You can find the voltage by finding this current* RILIM. 

    Please Note, this eFuse is not designed for very low currents like 0.1A and may have bad accuracy at those levels. 

    Click resolved if this answers your query. 

    Best Regards,
