Description

The UCC38531 Power Controller is designed to provide a self powered USB hub with a local 3.3V regulated voltage and four 5V regulated voltages for USB ports. Each of the 5V output ports is individually enabled for optimal port control. Each port also provides an overcurrent fault signal 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 shutdown mechanism, which disables the outputs should the internal junction temperature exceed 150°C.
