Figure 10. Application Configuration for Active High NOTE In the case of an Open Drain Active Low configuration, an external pull-up resistor is required on the OUT terminal. Changes to the ranges stated in Table 1 will impact the accuracy of the cell measurements. Table 1. Parameters PARAMETER EXTERNAL COMPONENT MIN NOM MAX UNIT Voltage monitor filter resistance RIN 900 1000 4700 Ω Voltage monitor filter capacitance CIN 0.01 0.1 1.0 µF Supply voltage filter resistance RVD 100 1 K Ω Supply voltage filter capacitance CVD 0.1 1.0 µF CD external delay capacitance CCD 0.1 1.0 µF 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.
