MA8608   USB 2.0 High Speed 4-port hub controller

The MA8608 is a high performance solution for USB 2.0 High Speed 4-port hub controller with fully compliant with Universal Serial Bus Specification 2.0. The controller inherits advanced serial interface technology to consume the least power when 4 DS (downstream) ports function simultaneously.

The MA8608 is an innovation that integrates function to comply with USB-IF “Battery Charging Specification Revision 1.2”, which supports fast charging function for portable devices. This feature turns MA8608 into a USB Charging Hub for “Universal Charging Solution”, (UCS) compliant battery based portable devices, promoted by GSMA. The dedicate port in MA8608 can handle the charging request when B.C. compliant portable device is detected on the downstream port. And, after the handshake has been completed, MA8608 allows portable devices to draw up to 900mA (High speed); 1.5A (Low/Full speed) from charging downstream ports (CDP) or 1.5A from dedicated charging port (DCP). The MA8608 also support APPLE iPad fast charging mode.

MA8608 adapt Single Transaction Translator (STT) and Ganged power management to achieve cost effective purpose. Users can also implement multiple Hub configuration options through external EEPROM.

MA8608 supports QFN24 package targets at mainstream stand along 4 ports Hub market.
