The GL652USB is an 8 port USB hub with 1 upstream port and 7 downstream ports. It uses an 8-bit RISC-like uC to encode/decode the host commands. The GL652USB is designed mainly for stand-alone hub and can also be integrated in PC mo therboard or any other devices to support USB hub function. The GL652USB can switch between selfpower and bus-power automatically without re-plug in. The GL652USB can be configured as individual mode or ganged mode for the power management of downstream port devices. To prevent from abnormal current consumption of downstream port devices, the GL652USB supplies power enable flags by reading the over-current flags. The GL652USB supports smart traffic indication through the LED lighting. The higher data traffic flows through one port, the higher frequency of that port's LED blinks. To minimize the power consumption, the GL652USB will turn LED off and stop the clock when they are suspended.
Maximum ratings are the extreme limits to which the GL652USB can be exposed without permanently damaging it. The GL652USB contains circuitry to protect the inputs against damage from high static voltages; however, do not apply voltages higher than those shown in the table. Keep VIN and VOUT within the range GND (VIN or V OUT) VCC. Connect unused inputs to the appropriate voltage level, either GND or VDD.
