Procurement Notes

Verify the specific suffix 'BH' against the manufacturer's latest documentation, as ordering suffixes can indicate variations in packaging or environmental compliance. Confirm that the 10-MFPS package type matches the target PCB footprint requirements. Check for any product change notifications (PCN) related to assembly source transfers or material updates. Ensure the lead time aligns with project schedules, as availability may vary. Validate RoHS and REACH compliance status for the intended market regulations.

Selection Notes

Select this component when a compact solution for bipolar stepper motor control is required. The integrated nature reduces external component count compared to discrete bridge drivers. Consider the 800mA output limit when sizing for motor torque requirements. The wide voltage range allows compatibility with various system power rails. Verify that the parallel interface timing meets the microcontroller or controller specifications.
