Battery Input 2
Figure 66. VBAT2 Measurement Process
The two auxiliary voltage inputs can be measured in similar fashion to the battery inputs, with no voltage dividers.
The input range of the auxiliary inputs is 0 V to VREF. Figure 67 and Figure 68 illustrate the process. Applications
for this feature may include external temperature sensing, ambient light monitoring for controlling an LCD
back-light, or sensing the current drawn from the battery.
