TITUSB2036VFR
Overview
The TUSB2036VFR is a 2-port or 3-port full-speed (12 Mbps) USB 2.0 hub controller designed for low-power applications. It integrates a 3.3-V ASIC logic core and USB transceivers into a compact 32-LQFP package, supporting both bus-powered and self-powered modes. This controller is optimized for simplicity, offering ganged or per-port power switching and overcurrent reporting without the need for complex external logic.
Why Choose This Part
The TUSB2036VFR simplifies design by integrating transceivers and supporting 6-MHz crystal or 48-MHz oscillator inputs. It features low power consumption with a 40mA operating current and a 1uA sleep mode, while push-pull PWRON outputs eliminate the need for external pull-up resistors.
Applications
Key Specifications
Getting Started
To begin development, refer to the Texas Instruments TUSB2036 datasheet for strapping pin configurations that define the number of downstream ports and power modes. Hardware designers should use the 32-LQFP footprint and ensure a 3.3V supply is provided to the VCC pins. If custom descriptors are required, an external I2C EEPROM can be interfaced to the device's 3-state EEPROM pins.
