TSD5402QPWPRQ1

Overview

The TSD5402QPWPRQ1 is an automotive-grade Class-D sensor driver amplifier manufactured by Texas Instruments. It operates on a single supply voltage ranging from 4.5 V to 18 V and delivers up to 8 W of output power into an 8-ohm load. The device features a shutdown function for power management and is housed in a 16-pin HTSSOP package. It supports surface-mount installation and functions within a temperature range of -40°C to +125°C. Key electrical characteristics include a common-mode rejection ratio of 63 dB, a power supply rejection ratio of 75 dB, and a total harmonic distortion plus noise of 0.05%.

Feature Summary

• Automotive qualified Class-D sensor driver amplifier
• Integrated shutdown capability for low-power states
• High power efficiency with 8W output capability

Applications

• Automotive sensor signal conditioning
• Class-D audio or sensor interface circuits
• Vehicle electronics requiring high-reliability amplification

Procurement Notes

Verify the specific suffix 'PWPRQ1' against the official datasheet to confirm package type, tape-and-reel specifications, and automotive qualification status. Ensure compatibility with your system's thermal requirements and supply voltage constraints before ordering. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing automotive systems that require a robust, single-supply Class-D amplifier for sensor driving applications. Consider the 16-HTSSOP package for space-constrained PCB layouts. Evaluate the 4.5V to 18V operating range against your vehicle's power bus stability. The AEC-Q100 qualification ensures suitability for harsh automotive environments.

Part Context

This part belongs to the TSD5402-Q1 series of automotive Class-D amplifiers. It is designed specifically for driving sensors and actuators in automotive environments. The Q1 suffix indicates automotive grade qualification, while PWPR denotes the specific 16-pin PowerTSSOP package and reel packaging configuration used for high-volume manufacturing.

Replacement Considerations

Consult the official Texas Instruments documentation for verified pin-to-pin compatible alternatives within the TSD5402-Q1 family. Do not substitute with non-automotive graded parts without validating thermal and reliability performance.
