drv593驱动多个TEC

Other Parts Discussed in Thread: DRV593, DRV8412, DRV594

你好,请问DRV593的驱动方式是PWM输出么?

如果驱动多个TEC,应该采用并联还是串联的方式呢?593的驱动电流最大好像只能达到2A。

还有,593和594的区别在哪里呢?

  • 如果您愿意采用PWM驱动模式, DRV8412是一颗性价比较高的方案:电流高达3A,并同时可以驱动四颗TEC, 或并联使用电流高达6~7A. 你可以打开以下链接找到所有的有关资料。

    DRV593/4是PWM输出。593/594的区别是;

    The PWM switching frequency may be set to 500 kHz

    or 100 kHz depending on system requirements. To

    eliminate external components, the gain is fixed at

    2.3 V/V for the DRV593. For the DRV594, the gain is

    fixed at 14.5 V/V.
