TPS2042P TI Power Distribution | 8-PDIP | 2-Ch, 0.5A, 2.7-5.5V

Product Overview

The TPS2042P from Texas Instruments is a dual-channel power-distribution switch designed for applications requiring precision current limiting and thermal protection. Housed in an 8-pin PDIP package, this device provides independent enable control for each channel, making it ideal for USB ports, peripheral power management, and hot-swap applications. With a continuous output current of 0.5A per channel and an operating voltage range of 2.7V to 5.5V, the TPS2042P ensures reliable power distribution in space-constrained designs.

Detailed Technical Specifications

Key Features

• Dual-channel independent power switch with overcurrent and thermal protection
• Low on-resistance (70 mΩ typical) minimizes power loss
• Fast transient response for capacitive loads
• Undervoltage lockout (UVLO) ensures proper startup
• Built-in soft-start to reduce inrush current
• Available in industry-standard 8-PDIP package for easy prototyping

Target Applications

• USB port power management in 5G base stations (e.g., Nokia AirScale)
