Description and Introduction

Single High Side Driver, Inverting Inputs, Current Sensing, Overcurent Detection and Shutdown Fault Output in a 8-lead SOIC package The IR2128S is a high-speed, high-voltage power MOSFET and IGBT driver from International Rectifier (IR). Here are the manufacturer's specifications, descriptions, and features:

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

### **Part Number:**  
IR2128S  

### **Description:**  
The IR2128S is a high-voltage, high-speed power MOSFET and IGBT driver with independent high- and low-side referenced output channels. It is designed for applications requiring high-side switching in half-bridge or full-bridge configurations.  

### **Key Features:**  
- **High Voltage Range:** Up to 600V  
- **Floating Channel for Bootstrap Operation**  
- **Gate Drive Supply Range:** 10V to 20V  
- **Undervoltage Lockout (UVLO) for Both Channels**  
- **Matched Propagation Delay for Both Channels**  
- **High-Side Output in Phase with Input**  
- **Low-Side Output Out of Phase with Input**  
- **3.3V, 5V, and 15V Logic Input Compatible**  
- **CMOS Schmitt-Triggered Inputs with Hysteresis**  
- **Low Di/dt Gate Driver for Better Noise Immunity**  
- **Output Source/Sink Current Capability:** 290mA / 600mA  
- **Lead-Free, RoHS Compliant**  

### **Applications:**  
- Motor Drives  
- Switch-Mode Power Supplies (SMPS)  
- Half-Bridge and Full-Bridge Converters  
- Uninterruptible Power Supplies (UPS)  
- Induction Heating  

### **Package:**  
- **SOIC-8** (Small Outline Integrated Circuit)  

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

Application Scenarios & Design Considerations

Alternative Part Number

  • FAN7382MX --: High-side and low-side gate driver with similar 600V rating and pin-compatible functionality, widely available and cost effective.
  • L6384E --: High-voltage half-bridge gate driver with comparable drive capability and bootstrap operation, suitable drop-in for many IR2128 applications.
  • IRS2186PBF --: Same vendor family but different series naming, offers robust high-side/low-side driving with matched timing characteristics.
  • L6387ED --: High-voltage high-side/low-side gate driver with comparable drive current and bootstrap operation, suitable drop-in replacement in many circuits.
  • L6388ED013TR --: High-side/low-side gate driver in SOIC-8 with comparable drive current and bootstrap operation, suitable drop-in for many IR2128 applications.
  • IRS2186SPBF --: Same vendor family lineage with higher drive current and identical SOIC-8 pinout, offering improved robustness as a functional upgrade.
