Resistors R₁, R₂ and R₃ connected in series are used to program the overvoltage threshold and battery monitor ratio. The resistor values required for setting the overvoltage threshold V_OV to 37 V and battery monitor ratio V_{BATT_MON} : V_BATT to 1:8 are calculated by solving Equation 3 and Equation 4.

Equation 4.

Equation 5.

For minimizing the input current drawn from the battery through resistors R₁, R₂ and R₃, TI recommends to use higher value of resistance. Using high value resistors adds error in the calculations because the current through the resistors at higher value become comparable to the leakage current into the OV pin. Maximum leakage current into the OV pin is 1 µA and choosing (R₁ + R₂ + R₃) < 120 kΩ ensures current through resistors is 100 times greater than leakage through OV pin.

Based on the device electrical characteristics, V_OVR is 1.23 V and battery monitor ratio (V_{BATT_MON} / V_BATT) is designed for a ratio of 1:8. To limit (R₁ + R₂ + R₃) < 120 kΩ, select (R₁ + R₂) = 100 kΩ. Solving Equation 3 gives R₃ = 3.45 kΩ. Solving Equation 4 for R2 using (R₁ + R₂) = 100 kΩ and R₃ = 3.45 kΩ, gives R₂ = 9.48 kΩ and R₁ = 90.52 kΩ.

Standard 1% resistor values closest to the calculated resistor values are R1 = 90.9 kΩ, R2 = 9.09 kΩ, and R3 = 3.48 kΩ.
