TPS2157IDGQ TI Power Distribution | 10-HVSSOP | 1.5A, 2.7-5.5V

Product Overview

The TPS2157IDGQ from Texas Instruments is a dual-channel, current-limited power-distribution switch designed for applications requiring precision current limiting and overcurrent protection. Housed in a compact 10-pin HVSSOP package, it operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for USB and general-purpose power management. Each channel provides a continuous output current of up to 1.5A with an accurate current-limit threshold of 1.5A (typical). The device features a low on-resistance of 70mΩ per channel, minimizing power dissipation. It includes thermal shutdown and reverse-current protection, ensuring robust operation in fault conditions. The TPS2157IDGQ is ideal for USB hubs, docking stations, and portable electronics where reliable power distribution is critical.
