MA8608
USB 2.0 High Speed 4-port hub controller
Description
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.
