PPK2 requested feature for PPK3

Hi,

we notice that the PPK2 doesn't like when we are letting it have the current reversed, ie when we are activating our PMIC to charge the battery.

This is a very good feature, to be able to allow current in both directions, and measure positive and negative current in the graph of PPK2-pc-software.

Are you planning on an updated PPK in version 3, this is a feature we would enjoy very much. 
It would help us debug easier, with not having to disconnect PPK2 when charging and then when connecting it back, our unit under test will lose all power (not wanted behavior), since it might show current bugs after disconnecting charger and we want to see what current it draws then.

Anyone else also want this feature in PPK3 ? 
PPK2 is missing in the TAGS btw, can you add it?

Best regards,

Johan

  • Hi !

    I would like to request a feature missing for upcoming PPK3.

    * Voltage measurement.

    I will explain. We do measure the low currents for our product to have a very long battery life (draw about 400uA continuously avg)

    But, there are sometimes bugs like after 5 or 10 days of continuous running, where a larger 16mA current will be drawn. And not seeing the battery pole voltage cannot help us determine if we have a drop below accepted range for all IC:s or if we have a dropout or if it is some other problem. We notice one chip is becoming restarted for reason for is unknown (probably voltage related our guess). I.e. we might need to increase some capacitance on board to solve that. But not being able to measure voltage along with current limits this.

    Today we will need to use OTII instead since it has this feature.

    If you can add it to PPK2 it would make it much more usable.
