MCHPUSB3503T-I/ML
Overview
The Microchip USB3503T-I/ML is a three-port, low-power USB 2.0 hub controller designed for embedded applications. It supports both Hi-Speed (480 Mbps) and Full-Speed (12 Mbps) data rates, allowing for flexible connectivity solutions. This IC is ideal for adding multiple USB ports to devices with limited native USB host capabilities.
Why Choose This Part
This USB hub controller offers low power consumption, with active transfer currents as low as 45mA for a single active downstream port and standby current of 3.1uA. Its compact 32-pin SQFN package with a 0.5mm pitch is suitable for space-constrained designs. The operating temperature range of -40C to 85C makes it suitable for industrial and consumer applications.
Applications
