6.8
The output FSO becomes HIGH when the watchdog is correctly serviced by the
microcontroller for the fourth time. As soon as either an under-voltage reset or watchdog
reset occurs, it is set LOW again. This feature is very useful to control critical applications
independent of the due function of the microcontroller e.g. to disable the power supply
in case of a microcontroller failure.
6.9
The sense comparator (early warning function) compares a voltage defined by the user
to an internal reference voltage. Therefore the voltage to be supervised has to be scaled
down by an external voltage divider in order to compare it to the internal sense threshold
V
protection diode. The microcontroller is given a pre-warning before an under-voltage
reset due to low input voltage occurs. The pre-warning is flagged by setting the interrupt
output INT low in normal mode, receive only mode and V
operation mode the sense function is inactive. Calculation of the voltage divider can be
easily done since the sense input current can be neglected. An internal blanking time
prevents from false triggering due to line transients. Further improvement is possible by
the use of an external ceramic capacitor switched between SI and GND (see Application
Diagram Figure 15).

be started.
Further to the reset threshold there is another supervisor threshold implemented, to
