Description and Introduction

IR2172 is not recommended for new designs. We recommend the IR2175 for new designs. The IR2172 is a high-voltage, high-speed power MOSFET and IGBT gate driver IC manufactured by International Rectifier (IR). Below are the key specifications, descriptions, and features based on the manufacturer's data:

### **Specifications:**  
- **Input Supply Voltage (VCC):** 15V (typical)  
- **High-Side Floating Supply Voltage (VB):** Up to 600V  
- **Output Current (Source/Sink):** 0.25A (typical)  
- **Propagation Delay:** 120ns (typical)  
- **Operating Frequency:** Up to 200kHz  
- **Common-Mode Transient Immunity (dV/dt):** 50V/ns (min)  
- **Undervoltage Lockout (UVLO):** Yes (for both VCC and VB)  
- **Temperature Range:** -40°C to +125°C  

### **Description:**  
The IR2172 is a monolithic gate driver designed for driving high-voltage N-channel power MOSFETs and IGBTs in half-bridge or other high-side switching configurations. It integrates a high-voltage level-shifting circuit, enabling robust operation in high-noise environments.  

### **Features:**  
- **Fully Integrated High-Voltage Gate Driver:** Eliminates the need for external level-shifting components.  
- **High Noise Immunity:** Robust against high dV/dt transients.  
- **Matched Propagation Delays:** Ensures precise timing control.  
- **Low Power Dissipation:** Optimized for efficiency.  
- **Compact Package:** Available in 8-lead PDIP or SOIC.  

For exact application details, always refer to the official IR datasheet.
