Figure 64. VBAT Example Battery Measurement Functional Block Diagrams, VDD = 2.7 V, VREF = 2.5 V.
Flowcharts which detail the process of making a battery input reading are shown in Figure 65 and Figure 66.
The time needed to make temperature, auxiliary, or battery measurements is given by:
where tREF is the reference delay time as given in Table 15.
