IR2184S Introduction
The IR2184S is a high-speed, high-voltage power MOSFET and IGBT driver, designed for driving both high-side and low-side channels in power electronics applications. It utilizes proprietary HVIC and latch-immune CMOS technologies, providing a rugged, monolithic construction that ensures reliable performance even in challenging environments. The driver is compatible with standard CMOS or LSTTL logic inputs, supporting voltages as low as 3.3V.
With a high pulse current buffer stage, it minimizes cross-conduction between the low and high sides, improving efficiency and reducing heat generation. The IR2184S can drive N-channel MOSFETs or IGBTs in high-side configurations, supporting voltages up to 600V. This makes it ideal for use in applications like motor control, inverters, and industrial power supplies, where efficient and reliable switching is essential for optimal system performance.
IR2184S Pinout
1. IN – Input for the logic signal to drive the high and low-side MOSFETs.
2. SD – Shutdown pin. When pulled low, it disables the outputs (LO and HO) and the internal logic.
3. COM – Common pin for the low-side driver. Connects to the low-side ground.
4. LO – Low-side output pin for driving the low-side MOSFET.
5. VCC – Power supply for the low-side driver circuitry (typically 10-20V).
6. VS – Source of the high-side MOSFET. Connects to the switching node of the high-side MOSFET.
7. HO – High-side output pin for driving the high-side MOSFET.
8. VB – Floating bootstrap pin for providing the gate drive to the high-side MOSFET.
