Early Warning Resistor Divider Adjust
The switching threshold can be set to the application’s needs by connecting an external voltage divider (
at pin “SI”. If the Early Warning function is not needed, it is recommend to connect the SI pin to the output voltage
pin Q.
When dimensioning the voltage divider, take into consideration that there will be an additional current constantly
flowing through the resistors.
With a voltage divider connected, the upper switching threshold for the monitored voltage

Sense Output “SO”
The sense output “SO” is an open collector output with an integrated pull-up resistor. In case a lower-ohmic “SO”
signal is desired, an external pull-up resistor to the output “Q” can be connected.
