DRV8832: DRV8832 Isense?

Part Number: DRV8832


HI Teams:

现阶段有个新项目需要用到电机驱动DRV8832,单电芯供电,直流有刷减速电机,对于PIN2-Current Sense功能有几个问题咨询一下,谢谢。

  • PIN2-Current Sense是对电机工作电流进行限制,对于瞬间大电流能否起到作用;若PIN2直接接地是关闭电流限制功能(即不进行限流),还是将电流限制在1A以内;
  • 若电机工作电流在8A~1A之间波动,偶尔出现瞬间电流到1.2A~1.5A,限流电阻建议设置为多大;
  • 基于第2点,若需要在PIN3-OUT1线上串联电感,请问电感该如何选型;
