Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix 'LTR' indicates tape and reel packaging when sourcing from distributors. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the component matches the NRND (Not Recommended for New Designs) status if applicable to long-term availability planning. Cross-reference the datasheet revision date to ensure all electrical characteristics align with current design requirements.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component for designs requiring high power density and simplified layout due to integrated GaN and driver. Consider the 650 V rating and 225 mΩ RDS(on) for efficiency targets. Evaluate the 6.5 A current capability against load requirements. Verify input voltage compatibility with the control logic, noting the 3.3 V to 15 V range. Assess thermal management needs given the industrial temperature range and package size.
