Microchip USB2512B-AEZG

USB集线器控制器USB3V ~ 3.6V

Overview

The USB2512B-AEZG is a 2-port USB 2.0 high-speed low-power Hub Controller IC for embedded USB solutions. The leveraging Microchip's innovative MultiTRAK™ technology that delivers industry-leading data throughput in mixed-speed USB environments, the USB251xB family is an USB port expansion solution for applications that demand ultra low power and a small footprint without compromising on performance. Over 30 programmable features including Microchip's unique PortMap, PortSwap and PHYBoost are designed to aid system designers in simplifying PCB layout and optimizing bill-of-material cost. Every downstream port of the USB251xB hubs can be enabled to support USB battery charging 1.1 specification as a Charging Downstream Port (CDP). A CDP provides universal battery charging capability to a compliant mobile phone or portable electronic device using a standard USB port.
