UCS2112 Description
The UCS2112 is a dual USB port power switch configuration which can provide 3.0A continuous current (3.4A maximum) per VBUS port with precision overcurrent limiting (OCL), port power switch enables, auto-recovery fault handling, undervoltage and overvoltage lockout, back-drive protection and back-voltage protection, and dynamic thermal management. The UCS2112 is well suited for both stand-alone and applications...
