TPS2052AD TI Power Distribution | 8-SOIC | 2-Ch, 0.5A, 2.7-5.5V

Product Overview

The TPS2052AD from Texas Instruments is a dual-channel, current-limited power-distribution switch designed for applications where heavy capacitive loads and short circuits are likely to be encountered. It integrates two 70mΩ N-channel MOSFETs with independent enable inputs, providing robust protection and control for USB ports and other peripheral power distribution. The device operates over a supply voltage range of 2.7V to 5.5V, making it suitable for both 3.3V and 5V systems. Each channel can deliver up to 500mA of continuous current, with accurate current limiting (±20%) and thermal shutdown protection. The TPS2052AD is available in the industry-standard 8-pin SOIC package, offering a compact solution for space-constrained designs.

Detailed Technical Specifications

Key Features

• Dual-channel, independent enable control
• Low on-resistance (70mΩ) minimizes voltage drop and power dissipation
• Accurate current limiting (±20%) ensures reliable protection
• Thermal shutdown protection prevents damage from overtemperature
• Reverse current blocking eliminates back-feeding
• Output discharge function quickly discharges output capacitance when disabled
• Wide input voltage range (2.7V to 5.5V) supports multiple logic levels
• Compact 8-SOIC package saves board space

Target Applications

The TPS2052AD is ideal for power distribution in a variety of systems, including:

• USB Ports/Hubs: Used in USB 2.0 and USB 3.0 hubs for overcurrent protection, such as in desktop computers, docking stations, and monitors (e.g., Dell U2723QE monitor).
