Figure 22. Basic UVLO Configuration

Figure 23. Basic Over-Voltage Protection

Figure 24. UVLO/OVP Divider

The impedance seen looking into the resistor divider from the UVLO and OVP pins determines the hysteresis

level. UVLO and OVP enable and disable thresholds are calculated using the equations in the table below for the

three-resistor divider illustrated in Figure 24.
