Industry’s first programmable USB power controller
The industry’s first programmable USB power controller features the UCS1001-1, UCS1001-2, and UCS1002 models and offers advanced USB based charging capabilities for engineers designing host devices such as notebook or desktop computers, monitors, docking stations, printers as well as dedicated ac/dc products such as wall adapters.
The UCS1001 and UCS1002 provide a single USB port power switch capable of up to 2.5-A continuous current as well as a USB 2.0 compliant data switch. For stand-alone mode it offers portable device charging or attach-detection output. It can auto-cycle through up to nine preloaded charger emulation profiles until charging commences for portable devices. The device also allows portable device charging when an application or host is in standby or in a sleep state. The UCS1002 allows users to create and implement custom charger emulation profiles and customized current limiting for the USB charging port that can be updated as needed. The chips provide protection features for legacy USB port power switches, dynamic thermal management, precise over-current protection, and over-voltage lockout. They are offered in a 20-pin QFN 4mm by 4mm package. (Samples available now.)
