Dual channel USB port power controller

Microchip Technology Inc. has expanded its programmable USB-port power controller portfolio with the addition of the dual-channel UCS2112. This new port power controller supports two ports, with eight programmable continuous current limits for each port, ranging from 0.53 to 3.0 Amps for faster charging times at higher currents. Features for protecting and increasing overall system uptime also include integrated current monitoring, precision current limiting, charge rationing and dynamic thermal management. The UCS2112 helps designers address a wide breadth of host devices, such as the laptops, tablets, monitors, docking stations and printers found in automotive, computing, education and aviation applications, as well as multi-port charging accessories and storage. This device has the flexibility of working individually or in concert with USB hubs, to create a complete charging and/or USB-communication system.
