9.2.4.2 Overvoltage Protection

In a similar way to the UVLO set point, the overvoltage protection set point is configured using the resistor divider, ROVP_TOP and ROVP_BOT connected to the OVP pin. Set the ROVP_TOP = 100 kΩ and, using Equation 2, calculate the value for ROVP_BOT. For an OVP = 6.5 V, ROVP_BOT = 10.7 kΩ. When choosing the OVP set point, the resistor divider must ensure that the device will still get enabled for the VIN used in the application. This is achieved by making sure that the VOVPF requirement is still met with the chosen resistor divider and that the VIN needed to meet the requirement is larger than the VIN used in the application. Equation 14 shows this VIN and VOVPF requirement to set the OVP point. For this particular application, the requirement is met as the result is 5.16 V.
