TPS2321ID TI Power Management IC | 16-SOIC | Dual-Channel, 0.5A, 2.7V-5.5V

Product Overview

The TPS2321ID 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-pin SOIC package, it integrates two 0.5A current-limited switches with independent enable inputs. 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. Its low on-resistance (typically 70mΩ per channel) minimizes power loss and heat dissipation. The TPS2321ID includes built-in thermal shutdown and overcurrent protection, ensuring reliable operation in demanding environments.
