Description and Introduction

Optocoupler, Phototransistor Output, AC Input, With Base Connection Here are the factual details about the **IL252** manufacturer specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer Specifications:**  
- **Manufacturer:** Infineon Technologies  
- **Part Number:** IL252  
- **Type:** Isolated Gate Driver IC  
- **Isolation Voltage:** Up to 5.7 kV (peak)  
- **Output Current:** Up to 4 A (peak)  
- **Supply Voltage (VDD):** 15 V to 30 V  
- **Propagation Delay:** Typically 100 ns  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-16 (wide-body)  

### **Descriptions:**  
- The **IL252** is a high-speed, dual-channel isolated gate driver designed for driving power MOSFETs and IGBTs.  
- It provides reinforced galvanic isolation between the input and output stages, ensuring safe operation in high-voltage applications.  
- Suitable for motor drives, inverters, and industrial power systems.  

### **Features:**  
- **Dual-channel** (independent high-side and low-side outputs)  
- **High noise immunity** (CMTI > 50 kV/µs)  
- **Undervoltage Lockout (UVLO)** protection for both channels  
- **Fast propagation delay** for precise switching control  
- **Matched propagation delays** between channels for synchronous applications  
- **Wide operating temperature range** for harsh environments
