Microchip UCS1003-1-BP

USB 专用充电端口（DCP），电源开关650µA4.5V ~ 5.5V

Overview

The UCS1003-1-BP is an USB Port Power Controller with charger emulation. It provides an 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, selectable active-high or -low enable, under-voltage 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 (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-BP will automatically charge a wide variety of portable devices, including USB-IF BC1.2, YD/T-1591 (2009), most Apple Inc., Samsung and RIM and many others.
