Introduction

MCZ33390EF is a series of 3-phase Line Driver with Enable (LDWE) and Fault output Interface designed for motor drive applications. It supports motor types such as brushless DC (BLDC) and permanent magnet synchronous motors (PMSM). This application field and working principle of this series of motor drivers will be discussed in the following text.

Application Field

The MCZ33390EF is specifically designed to drive a three-phase motor such as a brushless DC or a permanent magnet synchronous motor (PMSM). It supports step resolution up to 1/256 and provides a high up to 80V peak input voltage. It is particularly good for high voltage applications. With this application field, this driver is equipped to provide a reliable line supply voltage to attach electronic speed controls, motion control cards, or other machine controllers.

It can be used in a wide variety of applications such as industrial automation, robotics, machine tools, pumps, compressors, and elevators, just to name a few. It is also suitable for middle-high end range of AC Servo Drives, Nano Stockers in Semiconductor production, production automation systems and robot vacuum cleaners.

Working Principle

The MCZ33390EF is designed in accordance with the principle of driver circuitry. It is effectively a bridge-type Ported Voltage Stage. A bridge-type driver circuit is composed of N-channel metal oxide semiconductor field-effect transistors (MOSFETs), which are connected in a bridge configuration. The circuit is driven by an external voltage which is applied to the gate of the MOSFETs to vary their input resistance or the gate current flowing through them. This, in turn, changes their current carrying capability.

The overall circuit is based on the principle of converting a low voltage input power into high voltage output current. This is made possible by the use of MOSFETs that have higher input resistance and larger current carrying capability as compared to other transistors. This allows the circuit to attain higher supply voltages and currents as needed.

The MCZ33390EF is capable of producing high-voltage outputs up to 80V peak and is designed to drive three-phase motors such as BLDC motors and PMSM motors. It is designed to be compatible with various motor control systems such as pulse-width modulation (PWM), sine-wave PWM, and variable speed drives.
