Description and Introduction

Dimming Ballast Control, Brown-out Protection, Programmable Preheat Time, 1.8us Deadtime in a 16-lead SOIC Narrow package The IR21593S is a high-voltage, high-speed power MOSFET and IGBT driver manufactured by International Rectifier (IR). Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
- **International Rectifier (IR)**  

### **Specifications:**  
- **Output Current (Source/Sink):** 210mA / 420mA  
- **Supply Voltage (VCC):** 10V to 20V  
- **High-Side Floating Supply Voltage (VB):** Up to 600V  
- **Operating Frequency:** Up to 1MHz  
- **Propagation Delay (Typical):** 120ns  
- **Under-Voltage Lockout (UVLO) for VCC:** 8.4V (Turn-On), 7.6V (Turn-Off)  
- **Deadtime Control:** Adjustable via external resistor  
- **Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**  
- The IR21593S 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 independent outputs for controlling two power switches in a half-bridge configuration.  
- The device includes built-in deadtime control to prevent shoot-through in the half-bridge.  

### **Features:**  
- **Integrated Oscillator:** Eliminates the need for an external PWM controller.  
- **Adjustable Deadtime:** Allows optimization for different switching applications.  
- **High Noise Immunity:** Robust design for stable operation in noisy environments.  
- **Under-Voltage Lockout (UVLO):** Protects against insufficient supply voltage.  
- **Matched Propagation Delays:** Ensures precise timing between high-side and low-side outputs.  
- **Floating High-Side Driver:** Supports bootstrap or isolated power supply configurations.  

This information is based solely on the manufacturer's datasheet and technical documentation.
