TITUSB2046BIRHBT
Overview
The TUSB2046B is a 4-port full-speed USB 1.1 compliant hub controller designed for industrial environments. It provides one upstream port and four downstream ports with support for individual or ganged power switching and overcurrent detection. The device supports data rates up to 12 Mbps and is specifically rated for extended temperature operation.
Why Choose This Part
This integrated circuit features a simple hardware configuration via strap pins, eliminating the need for complex firmware programming. Its industrial temperature rating ensures reliable operation between -40C and 85C, and it includes logic for power management of downstream ports to protect the host controller from overcurrent events.
Applications
Getting Started
Engineers should consult the Texas Instruments TUSB2046B evaluation module (EVM) documentation for reference circuit layouts and power sequencing. Hardware configuration is handled through pull-up or pull-down resistors on pins like EXPM and BUSPWR to define hub characteristics without external software.
