TPS2045D TI Power Distribution Switch | 8-SOIC | 0.5A, 2.7-5.5V

Product Overview

The TPS2045D from Texas Instruments is a single-channel, current-limited power-distribution switch designed for applications where heavy capacitive loads and short circuits are likely. It integrates a 70mΩ N-channel MOSFET with a charge pump, providing a controlled rise time to limit inrush current. The device operates over a supply voltage range of 2.7V to 5.5V and delivers up to 0.5A of continuous current. It features thermal shutdown, overcurrent protection, and an enable input for power management. The TPS2045D is available in the 8-pin SOIC package, making it suitable for space-constrained designs.
