The ADM2914 is a quad voltage supervisory IC ideally suitedfor monitoring multiple rails in a wide range of applications.
Each monitored rail has two dedicated input pins, VHx and VLx, which allow each rail to be monitored for both overvoltage (OV) and undervoltage (UV) conditions. A common active lowundervoltage (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. Thethree-state SEL pin determines the polarity of the third andfourth inputs, that is, it configures the device to monitorpositive or negative supplies.
The device incorporates an internal shunt regulator that enablesthe device to be used in higher voltage systems. This featurerequires a resistor to be placed between the main supply rail andthe VCC pin to limit the current flow into the VCC pin to no greater than 10 mA. The ADM2914 uses the internal shuntregulator to regulate VCC if the supply line exceeds the absolute maximum ratings.
The ADM2914 is available in two models. The ADM2914-1offers a latching overvoltage output that can be cleared by toggling the LATCH input pin. The ADM2914-2 has a disablepin that can override and disable both the OV and UVoutputsignals.
The ADM2914 is available in a 16-lead QSOP package. Thedevice operates over the extended temperature range of −40°Cto +125°C.
