UCS1002-1

Programmable USB Port Power Controller

with Charger Emulation

Datasheet

PRODUCT FEATURES

General Description

Features

Port power switch with two current limit behaviors

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.



—

2.9 V to 5.5 V source voltage range

Up to 2.5 A current with 55 mΩ On Resistance

Over-current trip or constant current limiting

Soft turn-on circuitry

Programmable current limit

Dynamic thermal management

Under- and over-voltage lockout

Back-drive, back-voltage protection

Latch or auto-recovery (low test current) fault handling

Selectable active high or low power switch enable

BC1.2 VBUS discharge port renegotiation function



Selectable / automatic cycling of USB data line

charger emulation profiles

—

Customizable emulation profile uses a unique stimulus

and response method useful for future profiles*

Supports charger emulation

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.

—

Allows for active cables

USB-IF BC1.2 charging downstream port (CDP) &

dedicated charging port (DCP) modes, YD/T-1591, and

most Apple and RIM protocols standard; others as

defined via the SMBus 2.0 / I²C^®

USB 2.0 compliant high-speed data switch (in Pass-

through and CDP modes)

Nine preloaded charger emulation profiles for maximum

compatibility coverage of peripheral devices

One custom programmable charger emulation profile

for portable device support for fully host controlled

charger emulation

—



Fault Alert open-drain output

Self-contained current monitoring

Low power Attach Detection and open-drain A_DET#



Ultra low power Sleep state

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

4 mm package.

Optional split supply support for VBUS and VDD for

low power in system standby states

Wake on Attach USB



Applications

SMBus 2.0 / I²C communications



Notebook and Netbook Computers

Tablets and E-book readers

Desktops and Monitors

Docking Stations and Printers

AC-DC wall adapters

—
