Hello.

Has anyone looked at figure 12, of AN86233, where current measurements, in both Deep sleep and Active, are performed?

It would be nice to know the Y-axis and X-axis scaling factors, which are not illustrated, in figure 12. Considering that measuring a few micro-amps and thousands of micro-amps, using the same Y-axis scaling factor might lead to inconsistent results.

Please see comments below.

Kind regards,

Andrew Mugisha

Hello Andrew,

The image is used to represent how the current changes in active and deep-sleep mode. The idea is to see how current changes in active and deep sleep mode in each time slot and use this information to find the average current consumption. With the setting shown in the image you will not be able to see both active and sleep current same time with the same accuracy. If you are interested in checking this, you can use a multimeter to measure the current.

Best Regards,
