Description and Introduction

High and Low Side Driver, Shutdown Input, High Creepage Package in a 16-pin DIP -2 leads package The IR2112 is a high-voltage, high-speed power MOSFET and IGBT driver with independent high- and low-side referenced output channels. Below are the key specifications, descriptions, and features from the manufacturer (Infineon Technologies, formerly International Rectifier):

### **Manufacturer:**  
Infineon Technologies (formerly International Rectifier, IR)  

### **Part Number:**  
IR2112  

### **Key Specifications:**  
- **Output Current (Source/Sink):**  
  - High-Side: 250mA (source), 500mA (sink)  
  - Low-Side: 250mA (source), 500mA (sink)  
- **Voltage Ratings:**  
  - High-Side Floating Supply Voltage (VB): Up to **600V** (max)  
  - Logic Supply Voltage (VCC): **10V to 20V**  
  - Output Supply Voltage (VDD): **10V to 20V**  
- **Switching Speed:**  
  - Rise Time (Typical): **120ns**  
  - Fall Time (Typical): **90ns**  
- **Propagation Delay:**  
  - High-Side: **120ns** (typical)  
  - Low-Side: **120ns** (typical)  
- **Deadtime (Between High & Low Outputs):** **520ns** (typical)  
- **Operating Temperature Range:** **-40°C to +125°C**  

### **Descriptions:**  
- The IR2112 is a **dual-channel gate driver** designed for driving high-side and low-side MOSFETs or IGBTs in half-bridge or full-bridge configurations.  
- It features **floating high-side drive capability** with bootstrap operation, eliminating the need for a separate high-side power supply.  
- The device includes **undervoltage lockout (UVLO)** protection for both high-side and low-side drivers.  

### **Features:**  
1. **Independent High- and Low-Side Outputs**  
2. **600V High-Side Voltage Rating**  
3. **3.3V, 5V, and 15V Logic Input Compatible**  
4. **Matched Propagation Delay for Both Channels**  
5. **Low Power Consumption**  
6. **CMOS Schmitt-Triggered Inputs with Hysteresis**  
7. **Internal Deadtime for Shoot-Through Protection**  
8. **Under-Voltage Lockout (UVLO) for Both Channels**  

### **Applications:**  
- Motor Drives  
- Switch-Mode Power Supplies (SMPS)  
- Inverters  
- Half-Bridge and Full-Bridge Converters  

The IR2112 is widely used in power electronics applications requiring high-voltage switching with robust gate drive capabilities.

Application Scenarios & Design Considerations

High and Low Side Driver, Shutdown Input, High Creepage Package in a 16-pin DIP -2 leads package

Alternative Part Number

  • FAN7392N --: High-side and low-side gate driver with similar 600V rating and logic input compatibility, pin-compatible in many designs.
  • L6384E --: High-voltage half-bridge gate driver with comparable drive capability and bootstrap operation, suitable drop-in for many IR2112 applications.
  • IRS2112PBF --: Same functional family from Infineon (formerly IR) with equivalent high/low-side driver specs, though from a different series naming.
  • FAN2112N --: High and low side gate driver with similar 600V rating and pin-compatible function, widely used as a direct substitute for the IR2112 family.
