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.
