UCC38531

PRELIMINARY

Universal Serial Bus Power Controller

DESCRIPTION

FEATURES

•

Fully USB Compliant

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.

•

Support Four 5V Peripherals and

One USB 3.3V Controller

•

Separate Power Enables

500mA Current Limiting per

Channel

The UCC38531 is configured by connecting the VREG to a regulated

5.5V 2A source.

•

Separate Open Drain Fault

Indicator for Each Channel

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 150°C.

•

3.3V Output for USB Controller

Available in 20 Pin DIP
