1 / 114 page  2023 Microchip Technology Inc. and its subsidiaries DS20006852A-page 1 UCS1002-3 Features • Port Power Switch with Two Current Limit Behaviors - 2.9V to 5.5V Source Voltage Range - Up to 2.5A Current with 55 m on Resistance - Overcurrent Trip or Constant Current Limiting - Soft Turn-On Circuitry - Programmable Current Limit - Dynamic Thermal Management - Undervoltage and Overvoltage Lockout - Back-Drive, 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 - Customizable Emulation Profile Uses a Unique Stimulus and Response Method Useful for Future Profiles (Note 1) - Supports Charger Emulation - Allows for Active Cables - 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. and RIM® Protocols Standard; others as defined via the SMBus 2.0/I2C® Protocol - 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 - 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#) Pin • Ultra Low-Power Sleep State • Optional Split Supply Support for VBUS and VDD for Low-Power in System Standby States • Wake on Attach USB • SMBus 2.0/I2C Communications - Supports Block Write and Read - Multiple SMBus Addresses • WideOperatingTemperatureRange:-40°Cto+85°C • IEC61000-4-2 8/15 kV Electrostatic Discharge (ESD) Immunity • UL Recognized and EN/IEC 60950-1 (CB) Certified General Description The UCS1002-3 provides a USB port power switch for precise control of up to 2.5A continuous current with Overcurrent Limit (OCL), dynamic thermal manage- ment, latch, or auto-recovery (low-test current) fault handling, selectable active-low or active-high enable, undervoltage and overvoltage lockout, back-drive pro- tection 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 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 or provide charging, or both. In addition to Power Switching and Current Limiting modes, the UCS1002-3 automatically charges a wide variety of portable devices, including USB-IF BC1.2, YD/T-1591 (2009), most Apple Inc. and RIM®, and many others. Nine preloaded charger emulation profiles maximize the compatibility coverage of the peripheral devices. Additionally, 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 (Note 1). The UCS1002-3 also provides current monitoring to enable 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 UCS1002-3 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 Note 1: 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. Programmable USB Port Power Controller with Charger Emulation |
