TPS2041BDR

Power Distribution Switches, Load Drivers Overview

The TPS2041BDR is a single-channel, current-limited power distribution switch manufactured by Texas Instruments. It features an N-channel MOSFET configured for high-side switching with a typical on-resistance of 70 milliohms. The device operates within a supply voltage range of 2.7 V to 5.5 V and provides a continuous output current limit of 500 mA. It incorporates comprehensive protection mechanisms including fixed current limiting, thermal shutdown, and undervoltage lockout (UVLO). The component is housed in an 8-SOIC package and supports an operating temperature range from -40°C to +85°C.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'BDR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the active-low enable logic aligns with the system control interface. Ensure the SOIC-8 footprint matches the PCB layout specifications. Validate compliance with RoHS directives if environmental standards are mandatory for the end product.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single-channel solution with moderate current capacity is required. It is suitable for applications needing integrated protection without external sensing resistors. Consider the 70 milliohm on-resistance for efficiency calculations. Evaluate the thermal performance requirements relative to the SOIC-8 package dissipation capabilities under continuous load conditions.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS2041 family of USB power switches designed for portable electronics. It serves as a cost-effective alternative to discrete MOSFET solutions by integrating control logic and protection circuits into a compact surface-mount package. The series is widely utilized in consumer electronics where space constraints and reliability are critical design factors.

Power Distribution Switches, Load Drivers Replacement Considerations

The TPS2041BD is a tube-packaged variant of the same electrical specification. The TPS2041BDG4 is a lead-free version of the tube package. Verify pin compatibility and thermal characteristics before substituting with other single-channel high-side switches from different manufacturers.
