Description and Introduction

Half Bridge Driver, LO In Phase with RT, Programmable Oscillating Frequency, 0.6us Deadtime in a 8-lead SOIC package and different phase The IR21531S is a high-voltage, high-speed power MOSFET and IGBT driver with independent high- and low-side referenced output channels. It is manufactured by Infineon Technologies (formerly International Rectifier, IR).  

### **Key Specifications:**  
- **Supply Voltage (VCC):** 10V to 20V  
- **Output Current (Source/Sink):** 210mA / 420mA  
- **High-Side Floating Supply Voltage (VB):** Up to 600V  
- **Logic Input Voltage (VIN):** 5V logic compatible  
- **Operating Frequency:** Up to several hundred kHz  
- **Propagation Delay (Typical):** 120ns  
- **Rise/Fall Time (Typical):** 50ns / 35ns  
- **Deadtime (Typical):** 540ns  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions and Features:**  
- **Half-Bridge Driver:** Designed for driving both high-side and low-side N-channel MOSFETs or IGBTs in half-bridge configurations.  
- **Integrated Bootstrap Diode:** Simplifies circuit design by eliminating the need for an external diode.  
- **Under-Voltage Lockout (UVLO):** Protects against insufficient supply voltage for both high-side and low-side drivers.  
- **Matched Propagation Delays:** Ensures minimal timing mismatch between high-side and low-side outputs.  
- **CMOS Schmitt-Triggered Inputs:** Provides high noise immunity.  
- **Low Power Consumption:** Optimized for efficiency.  
- **Pb-Free and RoHS Compliant:** Environmentally friendly.  

The IR21531S is commonly used in applications such as switch-mode power supplies (SMPS), motor drives, and electronic ballasts.
