TERMINUS FE1.1S-BSOP28BPTR

A USB 2.0 high-speed 4-port hub controller with special features to support the GSMA "Universal Charging Solution" (UCS). It is fully compliant with the USB-IF "Universal Serial Bus Specification Revision 2.0" and "Battery Charging Specification Revision 1.1/1.2". It is a highly integrated, high-quality, and high-performance solution for USB 2.0 4-port hubs. With its compact size and ultra-low power consumption, it is the ideal choice for embedded applications as well as standalone hubs. Its high quality is ensured by design-for-test with comprehensive scan chains and built-in self-test modes, which enable testing of all high-speed, full-speed, and low-speed analog front-end (AFE) components during the packaging and test phases. It can be optionally configured to support Charging Downstream Ports as defined by the USB-IF Battery Charging Specification. With this feature enabled, the USB hub can be easily transformed into a charging station — a USB charging hub for battery-based portable devices compliant with the Universal Charging Solution.
