Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the current lifecycle status before procurement as this specific part number is listed as End-of-Life (EOL). Confirm availability through authorized distributors or check for active replacement recommendations provided in official documentation. Ensure that the required packaging format matches the available reel or cut tape options specified in the final production data sheets.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when a compact solution combining both high-side and low-side driving functions is required. The integrated nature reduces external component count compared to discrete driver and MOSFET combinations. Consider the 4.5 V to 18 V operating range and 3.3 V logic compatibility when designing the control interface. Evaluate thermal management requirements given the 100 W power dissipation rating and the specific PowerPak-32 package constraints.
