IR2156 is a high-voltage, self-oscillating half-bridge driver IC manufactured by International Rectifier (IRF).

The IR2156 is a high-voltage, self-oscillating half-bridge driver IC manufactured by International Rectifier (IRF).

Specifications:

  • Supply Voltage (VCC): 10V to 20V
  • High-Side Floating Supply Voltage (VB): Up to 600V
  • Output Current (Source/Sink): 210mA / 420mA
  • Operating Frequency Range: Adjustable via external RC components
  • Dead Time Control: Programmable (prevents shoot-through)
  • Under-Voltage Lockout (UVLO): Ensures proper operation
  • Temperature Range: -40°C to +125°C
  • Package Options: PDIP-8, SOIC-8

Descriptions:

The IR2156 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.

Features:

  • Self-Oscillating Design: No external clock required
  • Programmable Frequency & Dead Time: Adjustable via external components
  • High Noise Immunity: Robust against switching noise
  • Low Power Consumption: Optimized for efficiency
  • Fault Protection: Includes under-voltage lockout (UVLO)

This IC is commonly used in applications like electronic ballasts, DC-DC converters, and motor drives.
