Product Overview
The TPS2321IDR from Texas Instruments is a dual-channel power distribution switch designed for applications requiring independent control of two power domains. Housed in a compact 16-SOIC package, it integrates two 0.5A current-limited switches with enable logic, making it ideal for USB ports, hot-swap supplies, and general-purpose power management. The device operates over a wide input voltage range of 2.7V to 5.5V, ensuring compatibility with 3.3V and 5V systems. Its low quiescent current (typically 20µA per channel) and built-in thermal shutdown enhance system reliability.
