Procurement Notes

Verify the part status carefully before procurement as this specific model is listed as obsolete or end-of-life. Confirm availability through authorized distributors or secondary markets if new production units are required. Ensure the ordering suffix matches the exact package and tape specifications needed for your manufacturing process. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when designing systems requiring a compact, single-chip solution for BLDC motor control in portable media devices. It is appropriate for applications where space constraints limit the use of discrete drivers. Consider the thermal performance of the HSOP package and the specific voltage requirements of the motor load against the 3V to 14V operating window.
