TPS2034D TI Power Distribution | 8-SOIC | 2.7-5.5V, 0.5A

Product Overview

The TPS2034D from Texas Instruments is a single-channel, current-limited power-distribution switch designed for applications requiring precision current limiting and thermal protection. Housed in an 8-pin SOIC package, this device operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for various low-voltage systems. It features a fixed current limit of 0.5A (typical) with ±20% accuracy, ensuring reliable protection for downstream components. The TPS2034D integrates an N-channel MOSFET with low on-resistance (typically 70mΩ) to minimize power dissipation and voltage drop. Additional features include enable logic, overcurrent indication (OC flag), and thermal shutdown with hysteresis. This device is ideal for USB ports, peripheral ports, and other hot-swap applications where robust fault protection is required.
