Description and Introduction

3 Phase Driver, Inverting Input, 0.8us Deadtime 13-20 Vout in a 28-lead SOIC package The IRS21303DS is a high-voltage, high-speed power MOSFET and IGBT driver manufactured by International Rectifier (IR).  

### **Specifications:**  
- **Voltage Rating:**  
  - High-side voltage range: Up to 600V  
  - Low-side voltage range: 10V to 20V  
- **Output Current:**  
  - Source current: 210mA  
  - Sink current: 420mA  
- **Propagation Delay:**  
  - Typical: 150ns (high-side), 120ns (low-side)  
- **Dead Time (Typical):** 1.2µs  
- **Operating Frequency:** Up to 500kHz  
- **Supply Voltage (VCC):** 10V to 20V  
- **Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead SOIC  

### **Descriptions:**  
- Designed for driving high-speed MOSFETs and IGBTs in half-bridge configurations.  
- Features integrated high-side and low-side drivers with independent inputs.  
- Includes undervoltage lockout (UVLO) protection for both high-side and low-side drivers.  
- Matched propagation delays for both channels to minimize dead time.  

### **Features:**  
- **Floating High-Side Driver:** Allows operation with bootstrap or isolated supplies.  
- **CMOS/LSTTL Compatible Inputs:** Ensures easy interfacing with control circuits.  
- **Cross-Conduction Prevention:** Internal dead time insertion to prevent shoot-through.  
- **Under-Voltage Lockout (UVLO):** Protects against insufficient supply voltage.  
- **Low Di/dt Gate Drivers:** Reduces EMI and voltage spikes.  

This driver is commonly used in motor control, power inverters, and switch-mode power supplies.
