8.1.1 Design Requirements

Changes to the ranges stated in Table 8-1 will impact the accuracy of the cell measurements. Figure 8-1 shows each external component.

Table 8-1 Parameters
PARAMETER EXTERNAL COMPONENT MIN NOM MAX UNIT
Voltage monitor filter resistance RIN 900 1000 1100 Ω
Voltage monitor filter capacitance CIN 0.01 0.1 µF
Supply voltage filter resistance RVD 100 300 1K Ω
Supply voltage filter capacitance CVD 0.05 0.1 1 µF
Note:

The device is calibrated using an RIN value = 1kΩ. Using a value other than this recommended value changes the accuracy of the cell voltage measurements and VOV trigger level.
