3 说明

DRV8353M 系列器件是高度集成的栅极驱动器，适用于三相无刷直流 (BLDC) 电机应用。这类应用包括 BLDC 电机的场定向控制 (FOC)、正弦电流控制和梯形电流控制。该器件型号提供了可选的集成式分流放大器以支持不同的电机控制方案，还提供了降压稳压器，以为栅极驱动器或外部控制器供电。

DRV8353M 采用智能栅极驱动 (SGD) 架构，减少了 MOSFET 压摆率控制和保护电路通常所需的外部元件数量。SGD 架构还可优化死区时间以防止击穿问题，在通过 MOSFET 压摆率控制技术降低电磁干扰 (EMI) 方面带来了灵活性，并可通过 VGS 监控器防止栅极短路问题。强大的栅极下拉电路有助于防止不必要的 dV/dt 寄生栅极开启事件。

该系列器件支持各种 PWM 控制模式（6x、3x、1x 和独立模式），可简化与外部控制器的连接。这些模式可减少电机驱动器 PWM 控制信号所需的控制器输出数量。该系列器件还包括 1x PWM 模式，因此可通过内部阻塞换向表轻松对 BLDC 电机进行传感器式梯形控制。
