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.
