Description and Introduction

Halogen Converter Control IC in a 8-lead PDIP package. Features Auto Resetting Short Circuit Protection, Auto Resetting Overload ... The IR2161 is a high-voltage, high-speed power MOSFET and IGBT driver manufactured by International Rectifier (IRF). Here are the specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage (VCC):** 10V to 20V  
- **Output Current (Peak):** 1.0A (source), 1.4A (sink)  
- **Operating Frequency:** Up to 500kHz  
- **Propagation Delay:** 120ns (typical)  
- **Rise/Fall Time:** 50ns (typical)  
- **Input Logic Compatibility:** CMOS/TTL  
- **Under-Voltage Lockout (UVLO):** 8.7V (turn-on), 8.3V (turn-off)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin DIP or SOIC  

### **Descriptions:**
- The IR2161 is designed to drive high-side and low-side N-channel MOSFETs or IGBTs in half-bridge or full-bridge configurations.  
- It integrates a high-speed level shifter for high-side gate driving and includes dead-time control to prevent shoot-through.  
- Suitable for applications like motor drives, switch-mode power supplies (SMPS), and inverters.  

### **Features:**
- **Floating High-Side Driver:** Supports bootstrap operation for high-side drive.  
- **Matched Propagation Delays:** Ensures precise timing for switching applications.  
- **Dead-Time Control:** Prevents cross-conduction in half-bridge circuits.  
- **Low Power Consumption:** Optimized for efficiency.  
- **CMOS Schmitt-Trigger Inputs:** Ensures noise immunity.  
- **Under-Voltage Lockout (UVLO):** Protects against insufficient supply voltage.  
- **Cross-Conduction Prevention:** Built-in logic to avoid simultaneous high-side and low-side conduction.  

The IR2161 is a reliable driver for power switching applications requiring high efficiency and fast switching speeds.

Alternative Part Number

  • L6574D --: Half-bridge CFL ballast controller with integrated oscillator and driver, functionally similar to the IR2161 for fluorescent lamp ballast applications.
  • FAN7387 --: High-voltage self-oscillating half-bridge gate driver IC commonly used as a ballast controller, offering comparable drive capability and protection features.
  • IRS2153D --: Self-oscillating half-bridge driver in the same application space, suitable as a functional substitute when the integrated ballast control is not strictly required.
