Hi,
I have the question about what value of the CVM2 capacitance.
what do I need to concern, and how could I calculate the suitable capacitance?

Hi Viola,
Please reference section 8.3.1 External Components in the datasheet for a full list of required external components.

Hi David,
yes, I know it shown on datasheet.
But what value of bulk capacitor did I use?
I think 10uF means the MLCC not bulk.

Hi Viola,
Use bulk electrolytic capacitance to help source the low-frequency, high-value currents from the current that is driven through the motor winding. These capacitors usually are greater than 10 µF depending on the application requirements.
Place all bulk capacitors near the power supply module or power entry point of the board. TI recommends that each bulk capacitor have multiple vias connecting the pad to the respective power plane. TI also recommends that all bulk capacitors have low equivalent series resistance (ESR).
Please review the application note on Input and Output Capacitor Selection to help further details and examples.

David
