Product Overview
The TPS2226DB from Texas Instruments is a dual-channel power distribution switch designed for USB and general-purpose power management applications. It integrates two independent 1.5A current-limited switches with a 2.7V to 5.5V input voltage range, making it ideal for hot-swap and short-circuit protection. Housed in a compact 30-pin SSOP package, it offers low on-resistance (typically 70mΩ per channel) and built-in thermal shutdown.
