LM3481-Q1: Temperature -Vsense curve

Part Number: LM3481-Q1
Other Parts Discussed in Thread: LM5155

Hi team,

May I know if you have below temperature-Vsense curve? 100mV and 190mV corresponding to Vsense under which condition? Thank you

Thank 

Scarlett

    Hi Scarlett,

    We do not have temperature-Vsense curve. You may consider LM5155 with a much tighter current limit threshold tolerance over temperature.

    Hi Ji,

    If no curve, can you suggest if any relation between Vsense and temperature? when the min and max will occur? Is it just from device part to part variation and no link with temperature??

    Thank you

    Hi Scarlett,

    Like Feng already mentioned, I am afraid we have no detailed test data on any Vsense-temperature dependencies.
    From the datasheet, it looks to me like this min and max Vsense value are the worst case limits over all scenarios, including full temperature range, voltage/current ranges and part variance. Therefore, I would assume temperature is only one of several factors that could influence the Vsense voltage.

    Best regards,
