TPS2226DBR TI Power Distribution Switch | 30-SSOP | 1.5A, 2.7-5.5V

Product Overview

The TPS2226DBR from Texas Instruments is a dual-slot, dual-channel power distribution switch designed for CardBus and PCMCIA applications. It integrates two independent 1.5A current-limited power switches with controlled slew rate to minimize inrush current. The device operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for both 3.3V and 5V systems. Housed in a compact 30-pin SSOP package, it provides overcurrent, overtemperature, and undervoltage lockout protection, ensuring reliable operation in hot-swap and hot-plug environments.
