MIC4428YM-TR Integrated Circuits (ICs)

The MIC4428YM-TR is an integrated high-side or low-side field-effect transistor (FET) driver for driving n- and p-channel MOSFETs, bipolar transistors, and IGBTs. It is used for oscillator applications and drivers for Class D amplifiers. The device is part of a three-phase diode bridge rectifier, therefore it is constantly monitoring the voltage drop across each diode and controlling the MOSFET gate voltage. It is an ideal device for applications that require controlled switching of high-side and low-side MOSFETs, such as motor drives, SMPS, solenoid drivers, and lighting dimmers.

The MIC4428YM-TR\'s inputs and outputs enable a wide range of applications and provide high-efficiency power conversion and innovative feature sets. Its operating voltage range is 6.5 to 50V, reaching a maximum operating current of 13 Amps. It offers a wide range of operating frequency from 10 kHz to 200 kHz, depending on the load. It also has very high-speed turn on and turn off speed, with a fast response time to handle the changing needs of modern motor drives and products.

The MIC4428YM-TR utilizes a bootstrap technique, which provides a proper gate voltage to the MOSFETs during the switching process. This also offers protection against shoot-through current and over-current fault conditions. To prevent shoot-throughs, it features an active shoot-through protection (ASTP). This is a built-in feature that utilizes a precise timing delay to prevent current from flowing through the switches during the turn-on and turn-off phases. This reduces the amount of stress on the system’s components and improves the overall durability of the system.

In order to reduce noise, the device utilizes a low-impedance output stage for low-noise operation and also offers a control loop for overshoot voltage and under-voltage protection. This helps ensure the safe switching of the MOSFET and IGBT switches, further enhancing the overall efficiency of the circuit.

To protect the device from destructive thermal events and to ensure long life, it also includes various over-temperature and over-current protection features. It also has a built-in thermal shutdown feature, which shuts off the device if the temperature becomes too high and prevents any damage to the IC.

The MIC4428YM-TR also has an integrated pre-bias support feature and a wide range of features and enhancements to increase system efficiency and reliability. It is an ideal choice for applications that require a high-performance, reliable, and efficient MOSFET and FET driver.

The MIC4428YM-TR is a versatile device that is well-suited for a wide range of high-power applications. It offers advanced protection for MOSFETs, IGBTs, and power transistors, and is ideal for applications such as motor drives, SMPS, and lighting dimmers. Thanks to its wide range of features and enhancements, it is a great choice for applications that need protection and stability.
