TPS2553DBVR-1 Current-Limit Switch/Driver, Power Distribution IC
The TPS2553DBVR-1 from Texas Instruments is a precision adjustable current-limited power-distribution switch designed for USB ports and other hot-swap applications, featuring advanced protection and monitoring capabilities in a compact SOT-23-5 package. This integrated circuit provides robust over-current protection with user-adjustable current limits ranging from 75mA to 1.7A through an external resistor, making it ideal for protecting host controllers and power sources in portable devices, computer peripherals, and industrial systems. Its combination of precise current limiting, fast over-current response, and thermal protection ensures reliable operation and enhanced system safety in power management applications where port protection and fault management are critical requirements.
Key Features
This power-distribution switch features an exceptionally accurate current-limit threshold (±6% typical) with adjustable capability through a single external resistor, providing design flexibility for various application requirements. It offers a low typical on-resistance of 90mΩ (at 5V VIN) that minimizes voltage drop and power dissipation, while supporting continuous current operation up to 1.5A. The device incorporates rapid over-current response (2μs typical) with constant-current mode operation during fault conditions, and includes thermal shutdown protection that automatically disables the switch during overtemperature events. Additional features include reverse current blocking, under-voltage lockout protection, and a fault flag output that provides digital status indication for system monitoring and diagnostics.
