DRV8232 可配置 10mA ~ 1A峰值拉电流 和 20mA ~ 2A 峰值灌电流,应该如何选择合适的 拉/灌电流配置呢?跟外接MOSFET的哪些参数有关,并且是否有相应的计算公式?

您好,
请使用 IDRIVE 引脚/寄存器位设置来灌电流/拉电流配置。
有关相应的计算公式,请参考该FAQ:https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/796378/faq-selecting-the-best-idrive-setting-and-why-this-is-essential
