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 IR21531D is a high-voltage, high-speed power MOSFET and IGBT driver from Infineon Technologies. Below are the factual details about its manufacturer, specifications, descriptions, and features:

### **Manufacturer:**  
Infineon Technologies  

### **Specifications:**  
- **Output Current (Source/Sink):** 210 mA / 420 mA  
- **Supply Voltage (VCC):** 10V to 20V  
- **High-Side Floating Supply Voltage (VB):** Up to 600V  
- **Logic Input Voltage (VIN):** 5V logic compatible  
- **Operating Frequency:** Up to several hundred kHz  
- **Deadtime:** Adjustable via external resistor  
- **Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin PDIP or SOIC  

### **Descriptions:**  
The IR21531D is a self-oscillating half-bridge driver IC designed for driving power MOSFETs and IGBTs in high-voltage applications. It integrates a high-side and low-side driver with a built-in oscillator, eliminating the need for an external PWM controller.  

### **Features:**  
- **Integrated Oscillator:** No external PWM input required.  
- **Adjustable Deadtime:** Controlled via an external resistor.  
- **Under-Voltage Lockout (UVLO):** Protects against low supply voltage.  
- **High Noise Immunity:** Robust against switching noise.  
- **Matched Propagation Delays:** Ensures precise timing between high-side and low-side outputs.  
- **Low Power Consumption:** Suitable for energy-efficient designs.  

This information is based on Infineon's official datasheet for the IR21531D.
