TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 10.1 Application Information In the case of an Open Drain Active Low configuration, an external pull-up resistor is required on the OUT pin. Changes to the ranges stated in Table 1 will impact the accuracy of the cell measurements. Figure 8. Application Configuration Changes to the ranges stated in Table 1 will impact the accuracy of the cell measurements. Figure 8 shows each external component. Table 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 1K Ω Supply voltage filter capacitance CVD 0.1 µF CD external delay capacitance 0.1 1 µF OUT Open drain version pull-up resistance 100 k Ω to PACK+ 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.
