Introduction to MIC4225YMME-TR

The MIC4225YMME-TR is a small, low cost, dual gate driver suitable for a wide range of application fields. It can be used for gate driving of power MOSFETs, IGBTs, as well as for driving high-current sources and other applications that require high-current, low-voltage gate drive capability. The MIC4225YMME-TR is designed to provide a low-voltage, low-power, three-phase gate driver solution, with a switch current capability of up to 7A peak, and a working voltage of up to 20V DC.

Application Fields

The MIC4225YMME-TR can be used in a wide range of application fields, including power MOSFETs, IGBTs and other high-power applications. It is suitable for use in switching converters, lighting and motor controllers, AC servo motor drives, solar PV inverters, brake pedal drives, and other high-power applications. In addition, it can also be used for driving LED lighting applications such as LED arrays, LED strips, LED displays, LED boards and LED modules.

Working Principle

The working principle of the MIC4225YMME-TR is based on its dual gate driver configuration. Each phase of the three-phase system has its own gate driver block with its own voltage supply, providing a total of six active gates. The device can be used for low-side, high-side and half-bridge designs. The two gate driver blocks operate independently and can be configured to generate either symmetrical or asymmetrical outputs. In addition, the MIC4225YMME-TR also has adjustable timing and pulse width modulation (PWM) control, allowing the device to be used in a wide range of applications such as AC servo motor drives, solar PV inverters and other high-voltage applications. It also has built-in protection against over-current and over-voltage, and can operate with a minimum switching frequency of 3.75kHz.

Conclusion

The MIC4225YMME-TR is a small, low cost, dual gate driver suitable for a wide range of application fields. It is designed to provide a low-voltage, low-power, three-phase gate driver solution, with a switch current capability of up to 7A peak, and a working voltage of up to 20V DC. With its adjustable timing and pulse width modulation (PWM) control, the device can be used for driving power MOSFETs, IGBTs, AC servo motors, solar PV inverters, LED lighting applications and more. It also has built-in protection against over-current and over-voltage, making it an ideal choice for many applications.
