Description and Introduction

Ballast Control, Programmable Preheat Time and Run Frequency, Programmable Deadtime in a 16-lead SOIC Narrow package The IR2156S is a high-voltage, self-oscillating half-bridge driver IC manufactured by Infineon Technologies. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage (VCC):** 10V to 20V  
- **High-Side Floating Supply Voltage (VB):** Up to 600V  
- **Output Current (Source/Sink):** 210mA / 420mA  
- **Operating Frequency Range:** 20kHz to 200kHz  
- **Dead Time (Typical):** 1.2μs  
- **Maximum Duty Cycle:** 50%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**  
- The IR2156S is designed for driving MOSFETs or IGBTs in half-bridge configurations.  
- It integrates a high-side and low-side driver with a built-in oscillator, eliminating the need for an external PWM controller.  
- The IC includes under-voltage lockout (UVLO) protection for both high-side and low-side drivers.  

### **Features:**  
- **Self-Oscillating:** No external oscillator required.  
- **Programmable Frequency:** Adjustable via external resistor and capacitor.  
- **Dead Time Control:** Prevents shoot-through in the half-bridge.  
- **Under-Voltage Lockout (UVLO):** Ensures safe operation.  
- **Matched Propagation Delays:** Minimizes output distortion.  
- **Low Power Consumption:** Suitable for energy-efficient designs.  

This information is based on Infineon's official datasheet for the IR2156S.
