TPS2082DR

Power Distribution Switches, Load Drivers Overview

The TPS2082DR is a dual-channel high-side power distribution switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and provides an output current of 500 mA per channel with a maximum current limit of 1 A. The device features a typical on-resistance of 80 mΩ, with a maximum rating of 100 mΩ. It utilizes active-low enable inputs for control. The component is housed in an 8-pin SOIC package and is designed for surface-mount installation.

Power Distribution Switches, Load Drivers Feature Summary

• Dual-channel configuration for independent power distribution control
• Active-low enable inputs for logic-level interface compatibility
• Integrated current limiting protection for load safety
• Low on-resistance design to minimize power loss

Power Distribution Switches, Load Drivers Applications

• Portable consumer electronics power management
• Peripheral device hot-swapping interfaces
• Battery-powered system power sequencing
• USB hub power distribution circuits

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix DR indicates tape-and-reel packaging when sourcing components. Confirm the operating temperature range aligns with system requirements, as industrial variants may differ. Ensure the active-low enable logic matches the controlling microcontroller or FPGA output levels. Cross-reference the datasheet revision date to confirm pinout consistency with existing designs.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for applications requiring dual-channel high-side switching with moderate current capabilities. The 500 mA output per channel suits low-power peripherals rather than high-load motors. Consider the 80 mΩ on-resistance for thermal management in dense PCB layouts. Verify that the 2.7 V minimum supply voltage accommodates the lowest battery state in portable designs.

Power Distribution Switches, Load Drivers Part Context

The TPS2082 belongs to Texas Instruments' family of power-distribution switches designed for protecting and controlling power paths in portable devices. Unlike operational amplifiers such as the TLE2082, this part functions as a MOSFET-based switch rather than an analog signal amplifier. It integrates protection features typically found in dedicated power management ICs for USB and peripheral applications.

Power Distribution Switches, Load Drivers Replacement Considerations

The TPS2082D is the tube-packaged equivalent of the TPS2082DR. Both share identical electrical characteristics and pinouts. Substitution requires verifying that the packaging format change does not impact automated assembly processes. No functional differences exist between the D and DR suffixes regarding performance.
