Power Supply Recommendations

The DRV8329 family of devices is designed to operate from an input voltage supply (PVDD) range from 4.5 V to 60 V. A 10-µF and 0.1-µF ceramic capacitor rated for PVDD must be placed as close to the device as possible. In addition, a bulk capacitor must be included on the PVDD pin but can be shared with the bulk bypass capacitance for the external power MOSFETs. Additional bulk capacitance is required to bypass the external half-bridge MOSFETs and should be sized according to the application requirements.
