PRODUCTION DATA
Connect a resistor ladder as shown in Figure 9-9 for overvoltage threshold programming.
A disconnect switch is integrated between A and SW pins. This switch is turned OFF when EN or SLEEP pin is pulled low. This helps to reduce the leakage current through the resistor divider network during system shutdown state (IGN_OFF state).
When undervoltage functionality is not required then it is recommended to connect UVLO pin to EN or VS. It is recommended to connect OV pin to ground when overvoltage protection feature is not used.
