IRS20954SPBF

Audio Special Purpose Overview

The IRS20954SPBF is a protected digital audio driver designed for Class D amplifier applications. It features a floating PWM input and operates with a VCC supply range of 10V to 18V, supporting VS offset voltages up to ±100V. The device delivers a source current (Io+) of 1.0A and a sink current (Io-) of 1.2A. Key electrical parameters include a typical propagation delay of 90ns and selectable deadtime settings of 15ns, 25ns, 35ns, or 45ns. It features integrated bi-directional over-current protection with self-reset capabilities and is housed in a 16-pin SOIC narrow package.

Audio Special Purpose Feature Summary

• Integrated programmable bi-directional over-current protection with self-reset function
• Floating PWM input enables easy half-bridge implementation
• Selectable compensated preset deadtime for improved THD performances
• High noise immunity with ±100V high voltage ratings

Audio Special Purpose Applications

• Class D audio amplifier systems
• Audio systems requiring half-bridge configurations

Audio Special Purpose Procurement Notes

This component is obsolete and no longer manufactured by Infineon Technologies. Verify availability through authorized distributors for remaining stock or consider the recommended replacement, IRS20957SPBF, for new designs.

Audio Special Purpose Replacement Considerations

Infineon recommends using the IRS20957SPBF as a direct replacement. Verify pin compatibility and feature parity before substitution.
