Microchip USB2502-AEZG

USB2502-AEZG 일반적인 설명

When it comes to connecting multiple USB devices, the USB2502-AEZG hub controller IC is the go-to solution. Manufactured by Microchip Technology, this compact and cost-effective IC features an integrated 2-port USB 2.0 hub with support for full-speed and high-speed data transfer rates. Its small 32-pin QFN package and 3.3V power supply requirement make it suitable for space-constrained designs, and its compliance with USB 2.0 standards ensures full interoperability with a wide range of devices. Additionally, the USB2502-AEZG includes built-in over-current detection and protection mechanisms to ensure the safety of connected devices, making it a reliable choice for any application
