Working Principle of MIC4479YME-TR

The MIC4479YME-TR is an integrated circuit (ic) that consists of two independent n–channel High side and Low side MOSFET drivers. The driver is designed to drive n–channel enhancement and depletion FETs. The device consists of two input pins and four output pins.The two leftmost pins serve as inputs which receive the gate drive signals. The four rightmost pins are the output pins that drive the n–channel FETs.

The MIC4479YME−TR monitors the voltage at the inputs to determine the gate voltage of the high−side and low−side MOSFETs. When the voltage at one of the inputs is lower than the voltage at the other, the MIC4479YME−TR activates the low−side MOSFET and pulls the high−side MOSFET’s gate voltage to ground. Conversely, when the voltage at the other input is lower than the voltage at the first input, the MIC4479YME−TR activates the high−side MOSFET and pulls the low−side FET’s gate voltage to ground.

The MIC4479YME−TR features low supply voltage, low input capacitance, high accuracy, low offset and low propagation delay. It also features high temperature stability, low power dissipation and good thermal performance. It is able to switch MOSFETs with a minimum of current flow, reducing losses and improving efficiency in applications such as switched mode power supplies, motor drive, and automotive.

The MIC4479YME−TR is a versatile gate driver ic that is suitable for a wide range of applications. Its low voltage operation and low input capacitance make it ideal for applications with lower power consumption requirements, while its low offset and low propagation delay make it ideal for high accuracy and fast switching processes.
