INA214: INA214是否支持反向电流监测,如果支持,当输入反向电流时,输出电压还是0-vs递增?

Part Number: INA214

如题

  • 是的,INA214支持双电电流检测,并且输出电压还是0~Vs递增。 反向电流监测是通过REF引脚的接法来实现的,如Figure32. 输出响应通过IN+电压提高到REF之上,IN-降低到REF-之下来实现的,参考电压REF可以设置在0~V+任何电压范围内,但是通常,我们将REF电压设置为1/2Vcc.

    INA214的datasheet给出了反向电流监测的应用,可以参考Page24的8.2.2.3 Application Curve:
