IRS2092SPBF

Overview

The IRS2092SPBF is a high voltage, high performance Class D audio amplifier driver with an integrated PWM modulator and protection features. It operates within a supply voltage range of 10 V to 18 V and supports switching frequencies up to 800 kHz. The device delivers gate drive currents of 1.0 A (source) and 1.2 A (sink). Key electrical parameters include a maximum input offset voltage of ±15 mV, a typical THD+N of 0.01% at 1 kHz, and residual noise of 200 µVrms. It provides programmable bidirectional over-current protection with a maximum delay of 500 ns and selectable deadtime options of 25, 40, 65, or 105 ns.

Procurement Notes

Verify the specific ordering suffix 'SPBF' corresponds to the SOIC-16N package type when sourcing components. Confirm that the procurement matches the standard pack quantity of 45 units per tube as defined in the manufacturer's ordering information. Ensure compliance with RoHS standards and industrial qualification levels required for the intended application environment.

Selection Notes

Select this component for designs requiring a complete Class D audio amplifier solution using external MOSFETs. The device is suitable for applications needing high noise immunity and flexible PWM topology implementation due to open elements in the modulator section. Consider the available selectable deadtime settings to optimize total harmonic distortion performance based on the specific external switch characteristics.

Part Context

This part belongs to the IRS2092 family of protected digital audio amplifier drivers manufactured by Infineon Technologies. It is designed to work in conjunction with two external MOSFETs and minimal external components to realize a complete Class D audio amplifier with protection capabilities. The proprietary noise isolation technology allows high current gate drive stages and low noise error amplifiers to reside on a single silicon die.

FAQ

What are the available deadtime options?

The IRS2092SPBF offers selectable preset deadtime values of 25 ns, 40 ns, 65 ns, and 105 ns to improve THD performance.

How is over-current protection implemented?

It features programmable bidirectional over-current protection with a self-reset function. The low-side threshold is set via the OCSET pin, while the high-side uses the CSH pin.
