Power supplied to the PD_12 and the BAT_IN

  • PD_12 supply set the 12V

    • Checked the voltage at PD_12, and it is correctly 12V

  • BAT_IN set to voltages ranging from 9V to 15V

When first testing and setting the voltage to >12V, the comparator output measured around 12V. However, when turned down to <11V the output still remained high.

Restarting the test, both states produced a 0V output at the comparator.

Afterward, restarted the test but the output of the comparator outputted a voltage less than but proportional to the BAT_IN. For example, with the power supply set to 9V the comparator output was around 6V, with 13V around 7.5V and so on.

Next steps: the validation plan makes sense according to a schematic, will check the physical hardware.
