Device Overview

Summary

The UCS1001-3 provides a USB port power switch for precise control of up to 2.5 amperes continuous current with over-current limit (OCL), dynamic thermal management, latch or auto-recovery (low test current) fault handling, selectable active low or high enable, under- and over-voltage lockout, back-drive protection, and back-voltage protection.

Split supply support for VS and VDD is an option for low power in system standby states. This gives battery operated applications, like notebook PCs, the ability to detect attachments from a sleep or off state. After the Attach Detect is flagged, the system can decide to wake up and/or provide charging.

In addition to power switching and current limiting modes, the UCS1001-3 will automatically charge a wide variety of portable devices, including USB-IF BC1.2, YD/T-1591 (2009), most Apple® and RIM®, and many others. It prioritizes 12W charging, smartphones and tablets.  Nine preloaded charger emulation profiles maximize compatibility coverage of peripheral devices.

The UCS1001-3 is available in a 20-pin QFN 4 mm x 4 mm package.
