The 8-PDIP package of the IR2184 is a standard through-hole design, featuring a compact and user-friendly structure that suits various PCB layout requirements. Its package dimensions include a maximum length of 9.81 mm, a width of 7.11 mm, and a height of 3.94 mm, with a pin pitch of 2.54 mm and a typical pin thickness of 0.356 mm. This package type offers excellent mechanical strength and is well-suited for both manual soldering and automated assembly processes.
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.
The IR2184 is a high-voltage, high-speed gate driver designed for driving both high-side and low-side power MOSFETs or IGBTs in half-bridge configurations, commonly used in motor drives, inverters, and power supply circuits.
The IR2184 includes a high-pulse-current buffer stage and internal logic design to minimize driver cross-conduction, ensuring stable and efficient operation.
A test circuit typically includes a DC power supply, signal generator, and load resistors. VCC is connected to a low-voltage supply, COM is grounded, and VS and VB are connected to a high-voltage supply. The IN pin controls the high- and low-side outputs, and the SD pin enables or disables the driver.
