BD2242G-GTR

Power Distribution Switches, Load Drivers Overview

The BD2242G-GTR is a single-channel high-side power switch IC designed for USB power line applications. It integrates an N-channel MOSFET with a typical on-resistance of 89 mΩ and supports a load voltage range of 2.8 V to 5.5 V. The device features an active-high control input and provides a maximum output current of 1.7 A. Key electrical parameters include a fixed overcurrent detection threshold adjustable from 200 mA to 1.7 A via external resistors, a soft-start circuit, and an open-drain fault flag output. It operates within a temperature range of -40°C to +85°C and is housed in a compact SSOP6 package.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific ordering suffix GTR to confirm the tape and reel packaging format and quantity. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the SSOP6 package dimensions align with your PCB footprint design. Check the supply status as this is a standard-grade product not recommended for automotive equipment. Validate the active-high logic requirement against your system control signals.

Power Distribution Switches, Load Drivers Selection Notes

Select this model when a single-channel high-side switch with adjustable current limiting is required. The 89 mΩ on-resistance offers low power loss compared to higher resistance alternatives. The adjustable overcurrent limit allows customization for different load profiles without changing the IC. The open-drain fault output facilitates integration into systems requiring fault signaling. Consider the SSOP6 package size for space-constrained designs.

Power Distribution Switches, Load Drivers Part Context

The BD2242G-GTR belongs to ROHM's series of USB power switches. It is part of a family that includes variants like the BD2243G, which features active-low logic. This specific model is designed for general-purpose applications and is distinct from automotive-grade components. It complements other power management solutions by providing simple on/off control with robust protection features.

Power Distribution Switches, Load Drivers Replacement Considerations

The BD2243G-GTR is a direct functional substitute with identical electrical characteristics but utilizes active-low control logic instead of active-high. Designers must adjust their control signal polarity if substituting between these two models. Other members of the BD224x series may offer different channel counts or package options but require verification of pin compatibility and parameter alignment.
