1 / 138 page  2014-2015 Microchip Technology Inc. DS20005346B-page 1 UCS1003-1/2/3 Features • Port Power Switch with Two Current Limit Behaviors: - 2.9V to 5.5V source voltage range - Up to 3.0A current (2.85A typical) with 55 m on resistance - Overcurrent trip or Constant-Current Limiting - Soft turn-on circuitry - Selectable current limit - UCS1003-1 has programmable current limit via the SMBus 2.0/I2C protocol - Dynamic thermal management - Undervoltage Lockout (UVLO) and Overvoltage Lockout (OVLO) - Backdrive, back-voltage protection - Latch or auto-recovery (low test current) Fault handling - Selectable active-high or active-low power switch enable - BC1.2 VBUS discharge port renegotiation function • Selectable/Automatic Cycling of Universal Serial Bus (USB) Data Line Charger Emulation Profiles: - USB-IF BC1.2 Charging Downstream Port (CDP) and Dedicated Charging Port (DCP) modes, Chinese Telecommunications Industry Standard YD/T 1591-2009 and most Apple® Inc., Samsung and RIM® protocols standard - UCS1003-1 supports other charger emulation profiles as defined via the SMBus 2.0/I2C protocol - Supports 12W charging emulation - USB 2.0 compliant high-speed data switch (in Data Pass-Through, SDP and CDP modes) - Nine preloaded charger emulation profiles for maximum compatibility coverage of the peripheral devices - UCS1003-1 has one custom programmable charger emulation profile for portable device support for fully host-controlled charger emulation • Supports Active Cables • UCS1003-1 Supports Self-Contained Current Monitoring and Rationing for Power Allocation Applications • UCS1003-1 and UCS1003-3 have Low-Power Attach Detection and Open-Drain (A_DET#) Pin • UCS1003-2 has Charging Active (CHRG#) Open-Drain Pin • Ultra Low-Power Sleep State • Optional Split Supply Support for VS and VDD for Low Power in System Standby States • Wake on Attach USB (UCS1003-1 and UCS1003-3) • UCS1003-1 Supports SMBus 2.0/I2C Communications: - Supports block write and read - Multiple SMBus addresses • Wide Operating Temperature Range: -40°C to +85°C • IEC61000-4-2 8/15 kV Electrostatic Discharge (ESD) Immunity • UL Recognized and EN/IEC 60950-1 (CB) Certified Description The UCS1003-1/2/3 family of devices provides a USB port power switch for precise control of up to 3.0A continuous current (2.85A typical) with Overcurrent Limit (OCL), dynamic thermal management, latch or auto-recovery (low test current) Fault handling, select- able active-high or active-low enable, Undervoltage and Overvoltage Lockout, backdrive 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 (such as on-board computers) 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 UCS1003-1/2/3 will automatically charge a wide variety of portable devices, including USB-IF BC1.2, YD/T-1591 (2009), most Apple Inc., Samsung, RIM and many others. Nine preloaded charger emula- tion profiles maximize the compatibility coverage of the peripheral devices. Additionally, a customizable charger emulation profile is available in UCS1003-1 to accommodate unique existing and future portable device handshaking/signature requirements. The UCS1003-1 also provides current monitoring to allow intelligent management of system power and charge rationing for controlled delivery of current, regard- less of the host power state. This is especially important for battery-operated applications that want to provide power and do not want to drain the battery excessively. The UCS1003-1/2/3 family is available in a 4 mm x 4 mm 20-pin QFN package. Applications • Notebook and Netbook Computers • Tablets and E-Book Readers • Desktops and Monitors • Docking Stations and Printers • AC-DC Wall Adapters USB Port Power Controller with Charger Emulation |
