Fail safe output
After power-on (Vs > VPOR) or wakeup from VBAT -standby mode, the output FSO is set to
“HIGH”, if V1 is above the V1 threshold. FSO is set to “LOW” in case of V1 under voltage or
watchdog failure.
During V1-standby mode, FSO is HIGH unless a V1 under-voltage or watchdog reset
occurs. WD remains enabled in V1 standby mode until IV1 drops below 150uA. In VBAT -
standby mode, FSO is low. At exit from VBAT - standby mode, it goes to high as soon as V1
is stable.
At wakeup FSO remains high, provided that the watchdog is triggered successfully. It is set
low if the watchdog is not served during the long open window of if a V1 under-voltage
occurs.

Reset – generator
IF V1 is turned on and the voltage exceeds the V1 reset threshold, the reset output
“NRESET” is switched to “HIGH” after a 2ms reset delay time. This is necessary for a
defined start of the micro controller when the application is switched on.
As soon as an under voltage condition of the output voltage (V1 < VRT) for more than 8us
appears, the reset output is switched low again.
