Procurement Notes

Verify the complete part number including the suffix /NOPB to confirm lead-free status and RoHS compliance. Ensure the package variant matches the required SOIC-8 footprint. Confirm that the 1A output current specification meets the load requirements of the target MOSFETs. Check datasheet revisions for any updates to electrical characteristics or recommended operating conditions before finalizing procurement specifications.

Selection Notes

Select this component when a single-chip solution for driving two N-channel MOSFETs in a half-bridge arrangement is required. It is suitable for applications needing moderate switching speeds with rise and fall times around 1 microsecond. Consider the 1A peak drive current capability against the total gate charge of the connected MOSFETs. Verify that the 9V to 14V supply voltage range aligns with the system's available power rails.
