TPS25982: Ron vs current

Part Number: TPS25982

Do we have any data on the FET on-resistance vs load current?  The data sheet lists Ron for I = 2A.  what would the nominal resistance be at I = 10A or I = 15A?

    Hi Mark,

       We just mention the test conditions we use at FT for testing that particular parameter. Ideally the actual current shouldn’t matter as we use pulsed measurements to ensure the specified current doesn’t flow long enough to cause self-heating and introduce errors in the measurement. In an actual system, there will be self-heating and hence a drift in the on-resistance.
