DIV Reset is configured to be between 2 V and 4.2 V (for 5 V output voltage), or between
2 V and 2.75 V (for 3.3 V output voltage), depending on the voltage divider R5, R6
The undervoltage reset switching threshold can be adjusted according to the application’s requirements by
connecting an external voltage divider (R5, R6). For selecting the default threshold connect RADJ to GND.
With a voltage divider connected, the reset switching threshold
