TUSS4440TRTJT

Sensor And Detector Interfaces Overview

The TUSS4440TRTJT is a single-channel ultrasonic sensor interface IC manufactured by Texas Instruments. It operates within a supply voltage range of 5 V to 36 V and supports an extended industrial temperature range from -25°C to +105°C. The device utilizes a WQFN-20 package for surface-mount installation and communicates via an SPI interface. Designed specifically for transformer-driven ultrasonic sensors, it integrates necessary drive and signal conditioning circuitry into a compact form factor suitable for automotive and industrial sensing applications.

Sensor And Detector Interfaces Feature Summary

• Integrated transformer driver capability for direct connection to ultrasonic transducers
• Built-in signal processing for echo detection and distance measurement
• SPI digital interface for configuration and data readout

Sensor And Detector Interfaces Applications

• Automotive parking assistance systems
• Industrial object detection
• Level sensing in tanks

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'JR' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the component matches the required operating temperature range and voltage specifications for the target application environment before finalizing procurement orders.

Sensor And Detector Interfaces Selection Notes

Select this component when a single-channel solution with integrated transformer driving is required. Compare against the TUSS4470 series if direct drive without a transformer is preferred. Verify that the WQFN-20 package footprint aligns with the PCB layout constraints and thermal management requirements of the design.

Sensor And Detector Interfaces Part Context

This part belongs to the TUSS4440 family of ultrasonic sensor interfaces. It is distinct from the TUSS4470 series, which features a logarithmic amplifier and direct drive capability. The TUSS4440 is optimized for applications requiring transformer coupling between the driver and the piezoelectric element.

Sensor And Detector Interfaces Replacement Considerations

The TUSS4440TRTJR is a compatible variant within the same product line. Verify pin compatibility and functional equivalence before substitution. No other direct cross-model replacements are confirmed in public documentation.
