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. TLV6713 uv_sbvs331.gif

where

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

Choose an RTOTAL ( = R1 + R2) so that the current through the divider is approximately 100 times higher than the input current at the SENSE pin. Use resistors with high values to minimize current consumption (as a result of low input bias current) without adding significant error to the resistive divider.
