TPS2228DB TI Power Distribution | 30-SSOP | 1A, 2.7-5.5V

Product Overview

The TPS2228DB from Texas Instruments is a dual-slot, power-distribution switch designed for CardBus and ExpressCard applications. It integrates two independent 1A current-limited power switches with controlled slew rates to minimize inrush current. The device operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for various low-voltage systems. Housed in a compact 30-pin SSOP package, it provides overcurrent, overtemperature, and reverse-current protection, ensuring reliable operation in hot-plug environments.
