TUSB2077APTR Description

Short technical summary and product information.

The Texas Instruments TUSB2077APTR is an integrated circuit designed as a 7-port, full-speed USB 2.0 hub controller. It operates within a temperature range of 0°C to 70°C and is housed in a 48-LQFP package.

 

This hub controller is fully compliant with the USB 2.0 specification, supporting both full-speed (12Mbps) and low-speed operations on all downstream ports. It offers flexible power source modes, including self-powered mode supporting seven downstream ports and bus-powered mode supporting four downstream ports. The device features integrated USB transceivers and provides power switching and overcurrent reporting, which can be configured per port or ganged.

 

Designed for ease of integration, the TUSB2077APTR supports suspend and resume operations and includes a suspend status pin for external logic power-down. It can be customized with specific Vendor ID and Product ID using an external serial EEPROM, with a 3-state EEPROM interface allowing for shared use. The device also incorporates features like push-pull PWRON outputs to eliminate external pull-up resistors and noise filtering on OVRCUR for enhanced immunity to voltage spikes. It supports clock operation via a crystal input or a 48-MHz input clock and includes 3 LED indicator control outputs for monitoring hub/port status.
