Description and Introduction

DIGITAL AUDIO DRIVER WITH DISCRETE DEAD-TIME AND PROTECTION The IRS20124S is a high-speed, high-voltage power MOSFET and IGBT driver from International Rectifier (IR). Below are the factual specifications, descriptions, and features based on the manufacturer's data:

### **Manufacturer:** International Rectifier (IR)  
### **Part Number:** IRS20124S  

### **Description:**  
The IRS20124S is a dual-channel, high-speed power MOSFET and IGBT driver with independent high- and low-side referenced output channels. It is designed for applications requiring high noise immunity and fast switching performance.  

### **Key Features:**  
- **High-Speed Switching:** Propagation delays matched to within 50 ns.  
- **High Output Current:** 2.0 A source and 2.5 A sink current capability.  
- **Wide Voltage Range:**  
  - High-side floating supply voltage up to 600 V.  
  - Logic input compatible with 3.3 V, 5 V, and 15 V levels.  
- **Undervoltage Lockout (UVLO):**  
  - High-side and low-side UVLO protection.  
- **CMOS/LSTTL Input Compatible:**  
  - 3.3 V logic compatible inputs with hysteresis.  
- **Matched Propagation Delay:** Minimizes dead time for improved efficiency.  
- **High Noise Immunity:** Robust design for noisy environments.  
- **Operating Temperature Range:** -40°C to +125°C.  

### **Package:**  
- 14-lead SOIC (Small Outline Integrated Circuit) package.  

### **Applications:**  
- Motor drives  
- Switch-mode power supplies (SMPS)  
- Inverters  
- Class D audio amplifiers

Application Scenarios & Design Considerations

DIGITAL AUDIO DRIVER WITH DISCRETE DEAD-TIME AND PROTECTION

Alternative Part Number

  • FAN7392MX --: High-side and low-side gate driver with similar 600V capability and logic input, commonly used as a functional replacement for IRS20124S in half-bridge applications.
  • L6387ED --: High-voltage half-bridge gate driver with comparable drive current and bootstrap operation, suitable alternative when layout and pinout are adapted.
  • IR2113PBF --: Widely available high-side/low-side gate driver from the same vendor family with similar voltage and current ratings, often used as a cross-reference for IRS20124S designs.
