ADS125H02: Question

YUKIO YAMAMOTO
Prodigy 60 points

Part Number: ADS125H02

Hi Brian-san

I am always grateful for your help.

That's right. This is the circuit under experiment.
It is a circuit that measures the battery.
The power of the circuit is turned off and the battery is inserted and removed.
I wondered if it would be better to use a Zener diode as a countermeasure at that time.

Thank you.

    Hi Yamamo-san

    There are lots of options available for Zener diodes in terms of reverse breakdown voltages, making it relatively easy to find a diode to clamp the voltage between HV_AVDD and HV_AVSS when the supply voltage is exceeded. I have no specific device recommendations, but you can refer to Digikey (or your preferred distributor) to find a specific device. Since the ADS125H02 HV supply range is from 10 to 36 V, you may want to clamp these supplies when the potential difference is anywhere between 12-38 V (i.e. anything above expected supply ranges within the system).

    Let me know if this makes sense to you.

    It will be helpful.
    I would like to consider using a diode.
