Power Distribution Switches, Load Drivers datasheet and documents for TPS2042BDGNR

TPS2042BDGNR

Power Distribution Switches, Load Drivers Overview

The TPS2042BDGNR is a dual high-side power distribution switch manufactured by Texas Instruments. It operates within an input voltage range of 2.7 V to 5.5 V and provides two independent channels with a maximum output current of 500 mA per channel. The device features a typical on-resistance of 80 mΩ and incorporates fixed current limiting, thermal shutdown, and under-voltage lockout for comprehensive protection. Packaged in an 8-pin MSOP PowerPad (DG) surface-mount format, it supports active-low enable logic and functions as a USB switch or general-purpose load driver.

Power Distribution Switches, Load Drivers Feature Summary

Dual-channel high-side switching architecture for independent load control
Integrated fault protection including fixed current limiting and thermal shutdown
Low on-resistance design minimizes conduction losses and heat generation
Active-low enable inputs allow direct interface with standard logic levels

Power Distribution Switches, Load Drivers Applications

USB port power distribution and overcurrent protection
Peripheral device hot-swapping and power sequencing
Battery-powered equipment load management
General-purpose power distribution in embedded systems

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'G4' regarding lead-free compliance status, as datasheets may list obsolete variants without this designation. Confirm the package type matches the required MSOP-8 PowerPad footprint. Ensure the enable logic polarity aligns with the system's active-low requirements. Cross-reference the manufacturer part number against the latest official documentation to confirm current production status and availability.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when dual isolated high-side switching is required within a 5V rail environment. The low on-resistance makes it suitable for applications demanding minimal voltage drop under full load. Consider the thermal performance of the exposed pad for PCB layout optimization. Verify that the 500 mA continuous current rating meets the peak and steady-state demands of the connected loads.

Power Distribution Switches, Load Drivers Part Context

This device belongs to the TPS204x family of current-limited power distribution switches from Texas Instruments. It serves as a robust solution for protecting downstream circuits from short circuits and overloads. The family includes variants with different pin counts and current ratings, offering scalable power management options for portable and industrial electronics requiring reliable load switching capabilities.

Power Distribution Switches, Load Drivers Replacement Considerations

TPS2042BDGN is the tube-pack equivalent of this reel-part. TPS2042AD offers similar functionality in an SOIC-8 package. For automotive applications, consider the AEC-Q100 qualified TPS2042BQDRQ1 variant.
