The ADM12914 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 VCC pin to limit the current flow into the VCC pin at a level no greater than 10 mA. The ADM12914 uses the internal shunt regulator to regulate VCC if the supply line exceeds the absolute maximum ratings.
The ADM12914 is available in two models. The ADM12914-1 offers a latching overvoltage output that can be cleared by toggling the LATCH input pin. The ADM12914-2 has a disable pin that can override and disable both the UV and the OV output signals.
The ADM12914 is available in a 16-lead QSOP package. The device is specified over the extended temperature range of −40°C to +125°C.
