USB Port Power Controller with Charger Emulation

Datasheet

PRODUCT FEATURES

General Description

Features

Port power switch with two current limit behaviors



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.

—

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

Selectable 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

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.



Selectable / automatic cycling of USB data line

charger emulation profiles

—

Employs unique method and system for sampling

multiple profiles*

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.

—

UCS1001-3 and UCS1001-4 supports 12W charger

emulation

—

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

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

through and CDP modes)

—

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

4 mm package.

Nine preloaded charger emulation profiles for maximum

compatibility coverage of peripheral devices

Applications



Charging Active (UCS1001-3) or Attach Detection

(UCS1001-4) open-drain output



Notebook and Netbook Computers

Tablets and E-book readers

Desktops and Monitors



Ultra low power Sleep state

Optional split supply support for VBUS and VDD for

low power in system standby states

Docking Stations and Printers

AC-DC wall adapters



Wake on Attach USB (UCS1001-4)

Wide operating temperature range: -40 °C to +85 °C

IEC61000-4-2 8 / 15 kV ESD immunity

UL recognized and EN/IEC 60950-1 (CB) certified

* Unique technology covered under the following US patents pending: 13/109,446; 13/149,529; 13/173,287; 13/233,949; 13/157,282;

12/978,371; 13/232,965.
