摘要: 可以使用塔式系统设计TWR-MC-LV3PH的的低电压3相电机控制模块实现三相无刷直流(BLDC)和永磁同步电机(PMSM)电机控制功能。并且此外设模块,能够提供有效的塔式系统开发工具,一个完整的电机控制参考设计工具包,包括一个BLDC电机。

基本特性:

The 33937A is a Field Effect Transistor (FET) pre-drivers designed for three phase motor control and similar applications. The integrated circuit (IC) uses SMARTMOS? technology.

The IC contains three High Side FET pre-drivers and three Low Side FET pre-drivers.Three external bootstrap capacitors provide gate charge to the High Side FETs.

The IC interfaces to a MCU via six direct input control signals, an SPI port for device setup and asynchronous reset, enable and interrupt signals. Both 5.0 and 3.0 V logic level inputs are accepted and 5.0 V logic level outputs are provided.

方案介绍:

The 3-phase Low Voltage Motor Control board (TWR-MCLV3PH) is a peripheral Tower System Module. With one of the available MCU tower modules accommodating a selected microcontroller it provides a ready-made, softwaredevelopment platform for one-third horsepower off-line motors. Feedback signals are provided that allow a variety of algorithms to control 3-phase PMSM a..
