Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the NRND (Not Recommended for New Design) status before finalizing any design implementation. Confirm that the SOP-8 package dimensions and pinout match your PCB footprint requirements. Ensure the 6 V to 15 V supply voltage range aligns with your system's power architecture. Check for RoHS3 compliance if environmental regulations apply to your target market.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when a single-channel half-bridge driver is required for brushed DC motors operating between 6 V and 15 V. It is suitable for applications needing 1 A continuous current with integrated fault protection. Consider alternative parts if higher voltage ratings or multi-channel configurations are necessary. Verify thermal management capabilities given the 680 mW power dissipation limit in the SOP-8 package.
