IR2184 Driver: Pinout, Connection and Applications

IR2184 Introduction

The IR2184 is a high-voltage, high-speed driver designed for power MOSFETs and IGBTs, featuring dependent high and low side referenced output channels. Utilizing proprietary HVIC and latch-immune CMOS technologies, it ensures robust monolithic construction. 

It supports standard CMOS or LSTTL logic inputs down to 3.3V and includes high pulse current buffer stages to minimize cross-conduction. Its fl oating channel allows driving N-channel power MOSFETs or IGBTs in high-side configurations, operating up to 600 volts, making it ideal for demanding power electronics applications.

How to Test and Connect IR2184?

To test and connect the IR2184, follow these steps to ensure proper functionality and safe integration into the circuit.

Prepare a test circuit for the IR2184 with a DC power supply, signal generator, load resistors, and high-voltage protection. Connect VCC to a low-voltage supply and COM to ground. Attach the signal generator output to IN for switching control, and ground SD or connect it to VCC via a resistor to enable the chip. Connect VS and VB to a high-voltage supply for the high-side floating circuit, linking VS to the test load's high-side reference.

Gradually power up and monitor LO and HO outputs to ensure proper logic-driven signals. Test voltage and waveforms under no-load conditions to confirm signal stability. After validation, connect the IR2184 to a load (e.g., MOSFETs or IGBTs), ensuring correct high- and low-side driving. Adjust input frequency and duty cycle to evaluate response and performance.
