Description and Introduction

Half Bridge Driver, LO In Phase with RT, Programmable Oscillating Frequency, 0.6us Deadtime in a 8-pin DIP package and differenct phase The IR21531PBF is a high-voltage, high-speed power MOSFET and IGBT driver with an integrated oscillator. It is manufactured by Infineon Technologies (formerly International Rectifier).  

### **Key Specifications:**  
- **Supply Voltage (VCC):** 10V to 20V  
- **Output Current (Source/Sink):** 210mA / 420mA  
- **High-Side Floating Supply Voltage (VB):** Up to 600V  
- **Operating Frequency Range:** 5kHz to 1MHz  
- **Deadtime (Typical):** 1.2µs  
- **UVLO (Under-Voltage Lockout):** 8.4V (turn-on), 7.6V (turn-off)  
- **Package:** 8-Pin PDIP  

### **Descriptions and Features:**  
- **Integrated Oscillator:** Eliminates the need for an external clock signal.  
- **Programmable Frequency:** Adjustable via external resistor (RT) and capacitor (CT).  
- **High-Voltage Level Shifting:** Allows driving high-side N-channel MOSFETs or IGBTs.  
- **Cross-Conduction Prevention:** Built-in deadtime control to prevent shoot-through.  
- **Low Power Consumption:** CMOS input stage with hysteresis for noise immunity.  
- **Applications:** Used in half-bridge inverters, motor drives, and switch-mode power supplies (SMPS).  

This driver is designed for efficient and reliable switching in power electronics applications.
