Absolute/Ratiometric Selection
Absolute and Ratiometric Selection configures GPIO ADC readings as Absolute (referenced to GND) or
Ratiometric (percentage of TSREF)- generally used for thermistor readings.
To display the absolute voltage of a GPIO’s specific AUX value, simply check the desired GPIO* box.
Unchecked boxes display ratiometric values.

AUX_CELL Configuration
Configures the device to provide a secondary cell measurement system.
To allow for secondary measurement of a battery cell, first choose the desired “AUX Cell Selection” from
the dropdown, press the “Write” command button, select the “AUX_CELL_SEL_EN” checkbox, and finally
press the “Write” command button once more. This should allow for the AUX_CELL column in the “Device
Information” section at the bottom of the GUI to display the chosen cell’s voltage.

Cell Balancing
This section will discuss the basic blocks of the Cell Balancing Tab.
5.1
Balancing Configuration
To configure cell balancing, use the drop boxes to configure the duty cycle time, cell balancing timers, and
balancing sequence shown in
. If desired, the cell balancing done comparator can be enabled
and the threshold set.
