MIC4480YM-T5

Gate Drivers are one of the most important components used in Power Management Integrated Circuits (PMICs). The MIC4480YM-T5 is one such Gate Driver that has a wide range of applications. In this overview we will discuss the application field and working principle of the MIC4480YM-T5.

Applications of the MIC4480YM-T5

The MIC4480YM-T5 is a high speed, high voltage Gate Driver. It is capable of driving both N-Channel and P-Channel power MOSFETs as well as IGBTs. The MIC4480YM-T5 is optimized for use in applications such as automotive and industrial motor control, inverters, uninterruptible power supplies (UPSs), SMPSs, and others. Its operation covers a wide range of operating frequencies, from DC up to 500kHz. The MIC4480YM-T5 also features a 5A peak source drive current capability and 5kVrms isolation voltage.

Working Principle of the MIC4480YM-T5

The MIC4480YM-T5 utilizes an ARM Cortex-M0 MCU core and embedded software to adjust the accuracy of its driver circuitry. This enables it to reduce the amount of time needed for the MOSFETs to rise and fall. This design has the added benefit of reducing electromagnetic interference (EMI) generated by the MOSFETs, in turn improving system performance.

The MIC4480YM-T5 is capable of driving both low and high side MOSFETs. The power supply can be connected to either side of the Gate Driver, enabling it to operate in both DC and AC circuits. The MIC4480YM-T5 also includes an integrated pulse width modulator (PWM) to adjust the on/off times of the MOSFETs.

The circuitry is protected against faults using overcurrent, overvoltage and capacitor voltage protection. These features reduce the chances of circuit failure, increasing system reliability and safety.
