... Such initialization takes place when the input voltage rises between 2.6 V about typical. The system is ready to operate when the input voltage has reached the minimum 2.7 V. Considering this, the NCN6024 will detect an Under-Voltage situation when the input supply voltage will drop below 2.35 V typical. When VDD goes down below the UVLO falling threshold a deactivation sequence is performed ...
