Microchip has today introduced three new programmable USB port power controllers, the UCS100X family. Providing advanced USB-based charging capabilities, the new power controllers are intended for designing host devices, such as laptops, tablets, monitors, docking stations and printers. The UCS100X family also offers dedicated AC-DC power-supply and charging products, such as wall adapters.

An expansion of the popular UCS1001 and UCS1002 series, Microchip new USB port power controller products are the UCS1001-3, UCS1001-4 and UCS1002-2. Offering higher current and priority charging for smartphones and tablets, the UCS1002-2 features a built-in current sensor that can report on the amount of charging current. This allows a system to optimise its charging current and allocate power appropriately.

The UCS100X USB port power controllers also feature additional support for active cables, such as the Apple Lightning connector, and 12W charging. The UCS100Xcan support future USB product designs via a flexible method for detecting and creating charging emulation profiles, allowing designers to update their systems as new products are introduced to the market. This increases compatibility with a wider range of existing products.

Key features:

Microchip’s UCS100X family offers programmable charging emulation,
Integrated current sensor supports wider charging compatibility at higher currents,
Enables systems to be updated as new products are introduced,
Ensures compatibility with a wider range of existing products.

The UCS100X family is supported by Microchip’s new UCS1001-3/ UCS1001-4 Evaluation Board (ADM00540) priced at $24.99, and UCS1002-2 Evaluation Board (ADM00497) priced at $90.00, both of which are available today.

The UCS1001-3, UCS1001-4 and UCS1002-2 are available now for sampling in a 20-pin QFN package.
