Procurement Notes

Verify the Not Recommended for New Design (NRND) status before finalizing any procurement plans, as this designation indicates that the manufacturer does not recommend using this component in new designs. Confirm availability through authorized distributors, noting that standard factory production times may be extended due to the end-of-life lifecycle stage. Ensure all technical specifications align with current system requirements prior to ordering.

Selection Notes

Select this component when a dedicated single-phase BLDC solution is required for low-power applications. The integrated driver structure simplifies design compared to discrete implementations. Consider the thermal performance limits given the 1.17 W dissipation rating and ensure the PCB layout supports the TSSOP-16 package footprint for adequate heat management during operation.
