Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest documentation to confirm compliance with RoHS directives and material declarations. Ensure that the TSSOP-8 package dimensions match your PCB footprint requirements precisely. Cross-reference the ordering code with official ROHM Semiconductor catalogs to avoid confusion with similar variants in the BD82024 series. Confirm that the active-low control logic aligns with your system's microcontroller or driver interface specifications before finalizing procurement.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when designing systems requiring multi-channel high-side switching with moderate current capacity. The 1.7 A limit suits standard USB peripheral loads rather than high-power bus hubs. Consider the 115 mOhm on-resistance for thermal management calculations under continuous load conditions. The wide input voltage range allows compatibility with various logic levels and battery-powered sources. Evaluate the 20 ms turn-on time against system startup requirements to ensure it meets timing constraints.
