Application examples
a) The signal
UD can be utilized in battery powered systems to provide a warning in case of low batteries.
b) In case of power failure, the signal can serve to initiate data save routines.
Option D (“Save Data”, input undervoltage monitor)
Note: Output instead of input undervoltage monitor is
available on request (Option D1).
If the input voltage
Ui is below the adjustable threshold volt-
age
Ut, the control circuit for terminal D has low impedance.
Terminal D and Go– are connected to a self-conducting
field effect transistor (FET). A 0.5 W Zener diode provides
protection against overvoltages.

The voltage
Ut can be externally adjusted with a trim poten-
tiometer by means of a screwdriver. The hysteresis
UH of
Ut is <2%. Terminal D stays low for a minimum time
tlow min, in order to prevent any oscillation. Ut can be set to a
value between
Ui min and Ui max. It is important to note that
the FET can become conductive again when
UD > Ui – 3V.
