Original question:

DRV8836: Body diodes for EMF

DRV8836: Body diodes

Part Number: DRV8836

Hi,

We are going to use DRV8836 as the driver in our product. I saw someone has asked if the body diode can handle the reserved current when turning off the motor. You've given a positive answer, but may I ask how much current it can handle? What is the maximum value?

Thanks

Yuqing

    Yuqing,

    The body diode peak current would be higher than the 3.5A maximum OCP threshold. Also, the output current should not be higher than 3.5A.

    If a customer application needs the body diode to take care the output current in most of the time and that causes a thermal concern, they can add a Schottky diode in parallel with the internal FETs.
