电源管理

MOSFET 栅极驱动器是一种专用电路，可在高速开关应用和电源应用中有效驱动电源 MOSFET 栅极。 MOSFET 可在电机应用中提供适当极性，使转子按照有刷直流电机应用中所需的方向旋转。 BLDC（无刷直流）电机应用需要三个半桥 MOSFET 拓扑来换向 BLDC 电机。 电机控制系统由一个搭载了 FET 驱动器的 MCU 和三个半桥 MOSFET 组成。

智能三相 MOSFET 驱动器创新系列在无需硬件更改的情况下，可通过各种电机配置和电机控制算法进一步简化 BLDC 电机设计。 这些智能栅极驱动器集成了电源管理、过零检测、增益放大器以及采样/保持等支持电路，只需使用 MCU 中的 ADC，从而节省电路板空间和 BOM 成本。
