Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the 32-VQFN package dimensions match the design footprint. Ensure the 6 V to 38 V supply range aligns with the system power architecture. Check RoHS compliance status for regulatory requirements. Validate the operating temperature range against environmental conditions.

Selection Notes

Select this component for applications requiring integrated BLDC control with hardwired inputs. Consider the 300 mA output capability for low-to-medium power motors. Evaluate the 32-VQFN package size for space-constrained designs. Compare against other DRV830x series variants for pin compatibility or feature differences.
