Product Description

The TUSB2046BIRHBT is a 4-port Full-Speed Universal Serial Bus Hub that provides one upstream port and four downstream ports in compliance with the Universal Serial Bus (USB) specification as a full-speed hub. Because this device is implemented with a digital state machine instead of a microcontroller, no firmware programming is required. Fully compliant USB transceivers are integrated into the ASIC for all upstream and downstream ports. The downstream ports support full-speed and low-speed devices by automatically setting the slew rate according to the speed of the device attached to the ports. The configuration of the BUSPWR pin selects either the bus-powered or the self-powered mode. The TUSB2046B provides the flexibility of using a 6 or a 48MHz clock. The logic level of the TSTMODE terminal controls the selection of the clock source.
Integrated USB transceivers
3.3V Low power ASIC logic
One upstream port and 4 downstream ports
Two power source modes (self-powered mode, bus-powered mode)
All downstream ports support full-speed and low-speed operations
Power switching and over-current reporting is provided ganged or per port
Supports suspend and resume operations
Suspend status pin available for external logic power down
3-state EEPROM interface allows EEPROM sharing
Push-pull outputs for PWRON eliminate the need for external pull-up resistors
Noise filtering on OVRCUR provides immunity to voltage spikes
Supports low EMI emission achieved by a 6MHz crystal input
No special driver requirements
Supports 6MHz operation through a crystal input or a 48MHz input clock
Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
