GENERAL DESCRIPTION
The ADM2914 is a quad voltage supervisory IC ideally suited
for monitoring multiple rails in a wide range of applications.
Each monitored rail has two dedicated input pins, VHx and VLx,
which allows each rail to be monitored for both overvoltage
(OV) and undervoltage (UV) conditions. A common active low
undervoltage (UV) and overvoltage (OV) pin is shared by each
of the monitored voltage rails.
The ADM2914 includes a 1 V buffered reference output, REF,
that acts as an offset when monitoring a negative voltage. The
three-state SEL pin determines the polarity of the third and
fourth inputs, that is, it configures the device to monitor
positive or negative supplies.
The device incorporates an internal shunt regulator that enables
the device to be used in higher voltage systems. This feature
requires a resistor to be placed between the main supply rail and

the V CC pin to limit the current flow into the V CC pin to no
greater than 10 mA. The ADM2914 uses the internal shunt
regulator to regulate V CC if the supply line exceeds the absolute
maximum ratings.
The ADM2914 is available in two models. The ADM2914-1
offers a latching overvoltage output that can be cleared by
toggling the LATCH input pin. The ADM2914-2 has a disable
pin that can override and disable both the OV and UV output
signals.
The ADM2914 is available in a 16-lead QSOP package. The
device operates over the extended temperature range of ?40°C
to +125°C.
