    [SOLVED] Input Current Measurement of TLE 9879

    Hey, I am using a TLE 9879 evaluation kit to drive BLDC motor.
    I was trying to capture the input current of the kit from Jumper 5 using a oscilloscope. But the input current of the Kit was very small even when it is driving a Motor. Can we measure the input current of the motor using this jumper.

    you can not measure the input current of the motor using jumper 5. Jumper 5 is intended to open the VS line in order to measure the current flowing into the TLE9879. Please see the user manual of the board:

    But you can use the OP-Amp of the TLE987x to measure the current.
