9.2.2.1 Resistor Divider Selection

The resistor divider values and target threshold voltage can be calculated by using Equation 1 to determine VMON(UV).

Equation 1. GUID-6EE70D65-C074-4444-ABE8-6D0B127AEB99-low.gif

where

  • R1 and R2 are the resistor values for the resistor divider on the SENSEx pins
  • VMON(UV) is the target voltage at which an undervoltage condition is detected

Choose RTOTAL ( = R1 + R2) so that the current through the divider is approximately 100 times higher than the input current at the SENSE pin. The resistors can have high values to minimize current consumption as a result of low input bias current without adding significant error to the resistive divider. For details on sizing input resistors, refer to application report SLVA450, Optimizing Resistor Dividers at a Comparator Input, available for download from www.ti.com.
