Hello,

            if customer would like to do current sensing for DC motor to monitor current at any time. Do we have any reference schematics of current sensing for example for drv8832 or drv8802? Thank you.

    Hi Patrick,

    There are a few examples.

    One is shown on page 16 of the DRV8301 datasheet. It is an internal amplifier but does show how the current is converted into positive and negative values with variable gain.

    A second example is shown here LINK Page 4 of the Three-Phase Brushless Motor Driver Reference shows a single current amplifier.
