Programmable USB port power controllers

4 September 2013 Power Electronics / Power Management

Microchip has expanded its programmable USB port power controller portfolio with the three-member UCS100X family. These new controllers offer advanced USB-based charging capabilities for designing host devices, such as laptops, tablets, monitors, docking stations and printers; as well as dedicated AC-DC power supply and charging products, such as wall adaptors. They support active cables, such as the Apple Lightning connector, in addition to 12 W charging, and can support future USB product designs via a flexible method for detecting and creating charging emulation profiles. The UCS1002-2 features a built-in current sensor that can report on the amount of charging current, allowing a system to optimise its charging current and allocate power appropriately.
