Description and Introduction

Protected Digital Audio Driver with Floating PWM input The IRS20954STRPBF is a Class D audio amplifier IC manufactured by Infineon Technologies.  

### **Key Specifications:**  
- **Output Power:** Up to 200W (depending on configuration)  
- **Supply Voltage Range:** ±40V to ±100V (split supply)  
- **Switching Frequency:** Programmable from 50kHz to 600kHz  
- **Gate Drive Voltage:** 12V  
- **Protection Features:** Overcurrent, undervoltage, overtemperature, and fault reporting  
- **Package:** 16-Lead SOIC  

### **Descriptions and Features:**  
- **High-Efficiency Class D Operation:** Enables high-power audio amplification with minimal heat dissipation.  
- **Integrated PWM Modulator:** Simplifies design by including a built-in modulator.  
- **Programmable Dead Time:** Adjustable to optimize performance and reduce distortion.  
- **Fault Protection:** Comprehensive protection mechanisms enhance reliability.  
- **Low External Component Count:** Reduces system complexity and cost.  
- **High-Voltage Level Shifting:** Supports high-side gate drive for half-bridge configurations.  

This IC is commonly used in high-power audio amplifiers, home theater systems, and professional audio equipment.

Application Scenarios & Design Considerations
