Description and Introduction

Dual Low Side Driver, low voltage, high speed power MOSFET and IGBT drivers, Outputs in phase with inputs. Packaged in an SO-8 The IRS4427SPBF is a dual low-side MOSFET driver manufactured by Infineon Technologies.  

### **Specifications:**  
- **Configuration:** Dual low-side driver  
- **Output Current:** 1.4A (source) / 1.8A (sink)  
- **Supply Voltage (VDD):** 10V to 20V  
- **Propagation Delay:** 60ns (typical)  
- **Rise/Fall Time:** 30ns (typical)  
- **Operating Temperature:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions and Features:**  
- Designed for driving MOSFETs and IGBTs in low-side configurations.  
- Independent inputs for each driver channel.  
- Matched propagation delays for both channels.  
- Under-voltage lockout (UVLO) protection.  
- CMOS Schmitt-triggered inputs for noise immunity.  
- Outputs are in phase with the inputs.
