Description

General part information

UCS2112 Series

The UCS2112 is a dual USB port power switch configuration which can provide 3.0A continuous current (3.4A maximum) per VBUS port. The UCS2112 is well suited for both stand-alone and applications having SMBus/I2C communications.

For applications with SMBus, the UCS2112 provides per-port current monitoring and eight programmable current limits per switch, ranging from 0.53A to 3.0A continuous current (3.4A maximum). Per-port charge rationing is also provided ranging from 3.8 mAh to 246.3 Ah.

In Stand-alone mode, the UCS2112 provides eight current limits for both switches, ranging from 0.53A + 0.53A to 3A + 3A total continuous current.
