TPSI3050-Q1: Quiescent Current Draw When Not Enabled

Joss Chandler

Part Number: TPSI3050-Q1

Tool/software:

As the title says I am curious about what the idle current draw is from the IC when not enabled but powered on. I am trying to calculate the discharge rate of a battery when the system is in an idle state.

    Hello Joss Chandler,

    Thank you for reaching out to our team over E2E. 

    The TPSI3050-Q1 can be configured in 3 wire mode or 2 wire mode. In 2 wire mode the IC is entirely off and consumes no idle current. In 3 wire mode, the IC is always on and the idle current draw is set by the PXFR resistor. With the highest power setting (Rpxfr = 20k and Vddp = 5V), the TPSI3050-Q1 will have a idle current draw of 41.4 mA . 

    More helpful information can be found in our configuration calculator, which can be found here.

    If you share more information about your application, I may be able to provide better assistance. 

    Regards,

    Jack Hemmersmeier
