AUIRS2092S

Overview

The AUIRS2092S is an automotive-grade, high-voltage Class D audio amplifier driver featuring a built-in PWM modulator and protection circuitry. It operates with a low-side supply voltage range of 10 V to 18 V and supports floating input supplies up to ±100 V. The device provides typical gate drive currents of 1.0 A source and 1.2 A sink. It supports switching frequencies up to 800 kHz and includes programmable deadtime options (25/40/65/105 ns) and bidirectional over-current protection with self-reset functionality.

Feature Summary

• Integrated analog input Class D audio amplifier driver in a compact 16-pin package
• Programmable bidirectional over-current protection with self-reset function
• Floating inputs enable easy half-bridge implementation
• Start and stop click noise reduction for improved audio quality

Applications

• Automotive mini component stereo systems
• Automotive powered speaker systems
• Automotive audio power amplifiers

Procurement Notes

Verify the specific suffix 'S' corresponds to the SOIC-16 narrow body package variant. Confirm that the 'AU' prefix indicates compliance with automotive qualification standards per AEC-Q100. Ensure the procurement channel sources from authorized distributors to guarantee authenticity and traceability for automotive applications.

Selection Notes

Select this component when designing single-channel automotive audio systems requiring integrated protection and modulation. It is suitable for applications needing flexible PWM topology implementation via open elements. Consider the thermal resistance and operating temperature range (-40°C to 125°C) during PCB layout planning.

Part Context

This part belongs to the IRS2092 family of high-performance Class D audio amplifier drivers. The AUIRS2092S specifically denotes the automotive-qualified version manufactured by Infineon Technologies (formerly International Rectifier). It utilizes proprietary noise isolation technology to integrate high-current gate drive stages and low-noise error amplifiers on a single silicon die.

Replacement Considerations

The non-automotive grade IRS2092SPBF serves as a functional equivalent but lacks the specific automotive qualification requirements associated with the AU prefix.
