DRV8320: Flying capacitor value

Part Number: DRV8320

Hi, Team

The suggested value for flying capacitor on spec of DRV832x is 47nF. What if customer uses 22nF instead? Will there be potential issue / risk?

Thank you.

  • Hi Alvin,

    47nF is recommend value. This is to help support charge pump voltage output at low VM voltage (VM < 13V).

    If customer is operating at VM > 13V, then 22nF should be sufficient.
