10.1.1 Design Requirements

Changes to the ranges stated in Table 10-1 will impact the accuracy of the cell measurements. Figure 10-1 shows each external component.

Table 10-1 Parameters
PARAMETEREXTERNAL COMPONENTMINNOMMAXUNIT
Voltage monitor filter resistanceRIN90010001100Ω
Voltage monitor filter capacitanceCIN0.010.1µF
Supply voltage filter resistanceRVD1003001KΩ
Supply voltage filter capacitanceCVD0.050.11µF
Note:

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