USB3751A-1

In Production

Microchip's USB375x family of Hi-Speed USB switches were specifically designed to enable a range of applications to achieve single-port connectivity. Their design provides a substantial 1GHz of bandwidth, allowing for the passage of robust USB 2.0 signals. The USB375x family of highly-integrated USB 2.0 switches contains port detection and port protection within a small footprint package. The USB375x family provides excellent ESD performance along with over-voltage (OVP) and under-voltage (UVP) protection for the entire system. Microchip's RapidCharge Anywhere™ technology enables USB-IF Battery Charging Compliant detection capabilities for targeted portable devices, allowing for quick charging with a host PC or dedicated charger.
