BD2241G-GTR

Power Distribution Switches, Load Drivers Overview

The BD2241G-GTR is a single-channel high-side power switch IC from ROHM Semiconductor, designed for USB applications. It features an N-channel MOSFET output with a typical on-resistance of 110 mΩ and a maximum continuous output current of 820 mA. The device operates within a load voltage range of 2.7 V to 5.5 V and supports an open/switch interface with non-inverted input logic. Integrated protection functions include fixed over-current limiting, thermal shutdown, reverse current protection, and under-voltage lockout (UVLO). It is housed in a compact SC-74A (SOT-753) surface-mount package and is rated for an operating temperature range of -40°C to +85°C.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix GTR corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the SC-74A footprint matches your PCB design guidelines. Ensure the component meets RoHS compliance standards if mandated by your regional regulations. Cross-reference the datasheet revision date to confirm the accuracy of electrical parameters before finalizing procurement specifications.

Power Distribution Switches, Load Drivers Selection Notes

Select this model for applications requiring a single high-side switch with integrated protection in a small form factor. The non-inverted input logic simplifies control circuitry compared to inverted variants like the BD2240G. Consider the 110 mΩ on-resistance for thermal management calculations at the 820 mA load limit. Verify that the 2.7 V minimum operating voltage aligns with your system's supply rail stability during operation.

Power Distribution Switches, Load Drivers Part Context

This component belongs to ROHM's series of high-side power switches optimized for USB interfaces. It shares functional similarities with the BD2240G but differs in input logic polarity, offering a non-inverted control signal. The device is part of a broader family of load switches designed to provide robust protection and efficient power delivery in space-constrained consumer electronics.

Power Distribution Switches, Load Drivers Replacement Considerations

The BD2241G-GTR can be directly replaced by the BD2240G-GTR if the application requires inverted input logic instead of non-inverted. Both devices share identical electrical characteristics, package dimensions, and protection features, ensuring pin-to-pin compatibility without circuit redesign.
