SL6341

SL6341 is a 4-port, low-power, high-performance and configurable USB3.2 Gen 1x1 Hub Controller. It is compliant with the USB3.2 Revision 1.0 specification. SL6341 integrates USB3.0 Super Speed transmitter/receiver physical layer(PHY) and USB2.0 high speed PHY. It supports Super Speed, High Speed, Full Speed and Low Speed USB Connections and is fully compatible to all USB 3.0, USB2.0 and USB 1.1 hosts. The integrated 5V to 3.3V regulator enables SL6341 to be powered directly from 5V USB VBus, reducing BOM cost while offering high power efficiency. SL6341 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 compliant with BC1.2/1.1. It also allows portable devices to draw up to 1.5A from SL6341 charging downstream ports (CDP1) or dedicated charging port (DCP2). It can also enable systems to fast charge handheld devices even during “Sleep” and “Power-off” states. The BC1.2 Feature is disabled by default, Customers can modify the strapping pin for configuring it enabled.
