The software-controlled USBHub2x4 features four USB 2.0 ports with individually controlled data and power lines as well as independent current and voltage measurements. Each port delivers 2.5 A simultaneously for high-speed charging of all four devices and complies with the USB Battery Charge 1.2 specification. Two upstream ports enable multiple devices to be shared between two host computers, making the product suitable for software regression testing, smartphone software development and validation, manufacturing testing, burn-in and battery testing and USB device charge-curve testing. It is enclosed in a rugged aluminum housing and protected against ESD strikes to 15 kV (IEC 61000-4-2, level 4).
