TPS2041BDGNR

Power Distribution Switches, Load Drivers Overview

The TPS2041BDGNR is a single-channel current-limited power distribution switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and features an active-low enable input. The device integrates a high-side N-channel MOSFET with a typical on-resistance of 70 mΩ. It provides fixed current limiting at 500 mA, along with thermal shutdown and undervoltage lockout protection. The component is housed in an 8-pin MSOP PowerPAD package and is rated for operation over an extended temperature range of -40°C to +85°C.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'NR' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Texas Instruments to ensure authenticity. Check for RoHS compliance status if required by your manufacturing standards. Ensure the operating temperature range meets your system's environmental requirements. Validate the package type matches your PCB footprint design.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for single-channel high-side switching applications requiring integrated protection. It is suitable for designs needing precise current limiting without external sensing resistors. Consider the MSOP PowerPAD package for compact board space and improved thermal performance. Evaluate the 500 mA limit against your load requirements to ensure adequate headroom.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS2041 family of USB power distribution switches. It shares functional similarities with other members like the TPS2041BDR but differs in packaging. The family is designed for portable electronics and industrial interfaces requiring robust power management.

Power Distribution Switches, Load Drivers FAQ

What is the function of the EN pin?

The EN (Enable) pin controls the switch state. An active-low signal enables the output, while a high or floating signal disables it.

How does the device handle overtemperature conditions?

The TPS2041BDGNR includes thermal shutdown protection that automatically turns off the switch if the junction temperature exceeds safe limits.
