IR2184 Pinout Equivalent

1：Overview of the IR2184：

IR2184 is a high-performance 600V half-bridge gate driver chip launched by International Rectifier (IR, now acquired by Infineon). It adopts an 8-pin package. It can effectively drive power devices such as N-channel MOSFETs and IGBTs. It has a wide power supply voltage range (10V to 20V) and is compatible with 3.3V and 5V input logic, facilitating connection with different control circuits. IR2184 has a dual-channel undervoltage lockout protection function, which can timely close the output when the power supply voltage is abnormal to ensure circuit safety. Its high side adopts bootstrap technology to achieve high-end driving and has high anti-noise ability, enabling stable operation in a complex electromagnetic environment.
