UCS1001-3 UCS1001-4
USB Port Power Controller with Charger Emulation
PRODUCT FEATURES
Datasheet
General Description
The UCS1001 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 Detection is flagged, the system can decide to
wake up and/or provide charging.
In addition to power switching and current limiting
modes, the UCS1001 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. Nine preloaded charger emulation profiles
maximize compatibility coverage of peripheral devices.
The UCS1001 is available in a 20-pin QFN 4 mm x
4 mm package.
Applications
Notebook and Netbook Computers
Tablets and E-book readers
Desktops and Monitors
Docking Stations and Printers
AC-DC wall adapters
