DRV8332: VDD, PVDD, and GVDD Decoupling and Bulk Capacitance

Bryce Salmi94

Part Number: DRV8332

Looking at the DRV8332 datasheet the VDD Pin system design requirements talks about both VDD and GVDD. Is there any discussion about requirements of capacitance on GVDD and PVDD?

I see examples in the application circuits but there is no discussion about any actual requirements, best practices, etc?

    Bryce,

    Thanks for posting in the MD forum!

    I would recommend following the application circuits or the EVM guidance. If you wish to deviate from these instructions please let us know and we can discuss the potential effects.

    Regards,

    -Adam

    Thanks Adam, yeah I suppose I will. Would be nice to know any design minimums! My particular application tends to require use of Ceramic and maybe Tantalum capacitors. Electrolytic are a no go! uF is a premium!
