PRODUCTION DATA
Connect a resistor ladder as shown in Figure 8-5 for overvoltage and undervoltage 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 overvoltage or undervoltage condition is removed from input side then HGATE is turned on again.
