IR2166 is a high-performance, self-oscillating half-bridge driver IC manufactured by **Infineon Technologies (formerly International Rectifier, IOR)**.

The IR2166 is a high-performance, self-oscillating half-bridge driver IC manufactured by Infineon Technologies (formerly International Rectifier, IOR).

Key Specifications:

  • Input Voltage Range (VCC): 10V to 20V
  • Output Current (Source/Sink): 210mA / 420mA
  • Operating Frequency Range: Adjustable (typically up to 500kHz)
  • Dead Time Control: Programmable (50ns to 500ns)
  • Under-Voltage Lockout (UVLO): 8.7V (turn-on), 8.3V (turn-off)
  • Over-Current Protection: Cycle-by-cycle current limiting
  • Fault Protection: Over-temperature shutdown
  • Package Options: PDIP-16, SOIC-16

Descriptions:

The IR2166 is designed for driving MOSFETs or IGBTs in half-bridge configurations, commonly used in electronic ballasts, switch-mode power supplies (SMPS), and resonant converters. It integrates a high-side driver, low-side driver, oscillator, and protection features into a single IC.

Features:

  • Self-Oscillating Operation: Eliminates the need for an external oscillator.
  • Programmable Dead Time: Prevents shoot-through in the half-bridge.
  • Bootstrap High-Side Drive: Supports high-side MOSFET/IGBT switching.
  • Soft Start: Reduces inrush current during startup.
  • Over-Current Protection (OCP): Shuts down the driver in case of excessive current.
  • Over-Temperature Protection (OTP): Thermal shutdown for safety.

The IR2166 is optimized for efficiency and reliability in high-frequency power conversion applications.
