Atto Pilot Voltage and Current Sensor- Reverse Current

[Quad FRITZ]

Hi-

I used an Atto Sensor with Simon K regenerative breaking FW- it failed. I guess due to back current generated, giving a negative input for the sensor?

Any idea how to protect the Atto Sensor against reverse current to the battery?

I guess a simple antiparalell Shottky won´t do due to the delta U at the sensor input being too small? (futher more back voltage max is 0,3V?)

The datasheet can be found here: https://www.sparkfun.com/products/9028 I can not upload a PDF here...

Any help would be great because I really like the control performance when using regenerative breaking!

Thanks
Roman

How it failed? Back current is going to battery and not to sensors as far as I know.
