GL3510 电子元器件 GENESYS/创惟科技 封装QFN-48 USB 3.1 Gen 1集线器控制器

DESCRIPTION
Genesys GL3510 is a 4-port/2-port, low-power, and configurable hub controller. It is compliant with the USB 3.1 specification. GL3510 integrates Genesys Logic self-developed USB 3.1 Gen 1 Super Speed transmitter/receiver physical layer (PHY) and USB 2.0 High-Speed PHY. It supports Super Speed, Hi-Speed, and Full-Speed USB connections and is fully backward compatible to all USB 2.0 and USB 1.1 hosts. GL3510 has built-in 5V to 3.3V and 5V to 1.2V regulators, which saves customers’ BOM cost, and eases for PCB design.
GL3510 features the native fast-charging and complies with USB-IF battery charging specification rev1.2, it could fast-charge Apple, Samsung Galaxy devices, and any device complaint with BC1.2/1.1. It also allows portable devices to draw up to 1.5A from GL3510 charging downstream ports (CDP1) or dedicated charging port (DCP2). It can enable systems to fast charge handheld devices even during “Sleep” and “Power-off” modes.

FEATURES
