TPS2052D

Power Distribution Switches, Load Drivers Overview

The TPS2052D is a dual-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 8-pin SOIC package. The device provides high-side switching with a typical on-resistance of 345 mΩ per channel. Each output supports a continuous load current of up to 345 mA, with a fixed current limit designed to protect downstream circuits from overcurrent conditions. The component includes thermal shutdown and undervoltage lockout (UVLO) for enhanced reliability.

Power Distribution Switches, Load Drivers Feature Summary

• Dual-channel high-side power distribution with independent control
• Integrated current limiting and thermal protection mechanisms
• Undervoltage lockout ensures stable operation during low input conditions

Power Distribution Switches, Load Drivers Applications

• USB port power management and distribution
• Peripheral device power switching in embedded systems
• Battery-powered equipment load protection

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'D' indicates the SOIC-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering part number matches the required pin configuration and temperature rating for your application design.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for applications requiring dual isolated power rails with built-in fault protection. Compare against the TPS2052B series if lower on-resistance is critical, as the 'D' variant typically offers higher resistance but may differ in cost or availability. Validate that the 345 mA continuous current rating meets the maximum load requirements of the connected peripherals.

Power Distribution Switches, Load Drivers Part Context

This device belongs to the TPS205x family of USB power switches. It shares functional similarities with the TPS2052AD and TPS2052BD but differs in package type and specific electrical characteristics such as on-resistance. The family is designed for portable electronics and industrial control systems requiring robust power distribution.

Power Distribution Switches, Load Drivers Replacement Considerations

The TPS2052AD serves as a direct alternative with identical functionality but utilizes a different package. Verify pin compatibility and thermal performance before substitution. The TPS2052C is another option but operates at a higher minimum voltage of 4.5 V, which may not suit all 3.3 V or 5 V systems.
