Procurement Notes

Verify the exact suffix MTR indicates tape and reel packaging configuration when sourcing. Confirm the specific voltage rating and current capacity requirements against the official datasheet before procurement. Ensure compatibility with the target PCB footprint and soldering profile. Check for RoHS compliance status if required by your manufacturing standards. Validate that the supplier provides genuine Rohm Semiconductor products to avoid counterfeit risks.

Selection Notes

Select this component when a reliable high-side switch is needed for automotive loads. Consider its integrated protection features for simplified design without external sensing components. Evaluate the thermal performance requirements based on the expected load current and ambient temperature. Ensure the input logic levels match the controlling microcontroller or driver IC. Verify the package type fits the available board space constraints.

Part Context

This part belongs to Rohm's series of automotive-grade high-side drivers. These devices are engineered to replace discrete solutions, reducing board space and component count.
