Universal Serial Bus Power Controller

The UCC38531 Power Controller is designed to provide a self powered USB hub with a local 3.3V regulated voltage and four 5V regulated volt- ages for USB ports. Each of the 5V output ports is individually enabled for optimal port control. Each port also provides an overcurrent fault sig- nal indicating that the port has exceeded a 500mA current limit. The 3.3V linear Regulator is used to power the local USB Microcontroller This Regulator is protected with a 100mA current limit. The UCC38531 is configured by connecting the VREG to a regulated 5.5V 2A source. The 20-pin DIP package is protected by internal over-temperature shut- down mechanism, which disables the outputs should the internal junc- tion temperature exceed 150C. By Texas Instruments
