PRODUCT FEATURES

UCS1002-2

Programmable USB Port Power Controller

with Charger Emulation

General Description

The UCS1002 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 UCS1002 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.

As well, a customizable charger emulation profile is

available to accommodate unique existing and future

portable device handshaking / signature requirements.

This custom profile uses a unique stimulus and

response method referenced below.*

The UCS1002 also provides current monitoring to allow

intelligent management of system power and a Battery

Full option for controlled delivery of current regardless

of the host power state. This is especially important for

battery operated applications that want to provide power

in a standby and/or off state but do not want to drain the

battery excessively.

The UCS1002 is available in a 20-pin QFN 4 mm x

4 mm package.
