TPS2553DDBVR TI Power Distribution Switch | SOT-23-6 | 1.5A, 2.5-6.5V

Product Overview

The TPS2553DDBVR from Texas Instruments is a precision current-limited power distribution switch designed for applications requiring robust protection and accurate current limiting. Housed in a compact SOT-23-6 package, this device integrates a 70mΩ N-channel MOSFET with a programmable current limit threshold from 0.3A to 1.5A. It operates over a wide input voltage range of 2.5V to 6.5V, making it suitable for USB ports, industrial controls, and automotive infotainment systems. The device features fast transient response, thermal shutdown, and reverse current blocking, ensuring reliable operation in harsh environments.
