AT43312 Product details

Description
The AT43312 is a 5 port USB hub chip supporting one upstream and four downstream ports. The AT43312 connects to an upstream hub or Host/Root Hub via Port0 and the other ports connect to external downstream USB devices. The hub re-transmits the USB differential signal between Port0 and Ports[1:4] in both directions. A USB hub with the AT43312 can operate as a bus-powered or self-powered through chip’s power mode configuration pin. The AT43312 is pin- and function-compatible with the AT43311 and can be used as a replacement for the AT43310 with one pin modification.

Features
• Full compliance with USB spec Rev 1.0
• Four downstream ports
• Full speed and low speed data transfers
• Self-Powered or Bus-Powered modes of operation
• Per port overcurrent monitoring
• Individual port power switch control
• USB connection status indicators
