Overview

As portable devices continue to add more features and the system architecture becomes more complex, it is necessary to have more than one USB port to manage communications with internal and external peripheral devices. Microchip's low-power USB3503T-I/ML offers three downstream ports and is specifically designed for portable embedded applications where more than one USB port is required. The USB3503T-I/ML attaches to an upstream port via HSIC and supports Low, Full and Hi-Speed downstream devices on all enabled downstream ports. The package size has been minimized to save valuable PCB space, making the device well-suited for portable, battery-powered embedded systems where power consumption, reduced BOM cost and Battery Charger (BC) detection capabilities are critical design requirements.

The USB3503T-I/ML integrates the latest USB-IF Battery Charging 1.1 specification with Microchip's RapidCharge Anywhere™ functionality that dramatically reduces the time required for battery charging, while its flexible power regulators facilitate simple design into battery-powered devices. Microchip's complimentary and confidential USBCheck™ online design review service is available for customers who select the USB3503T-I/ML for their application design-in.*
