Analog Devices ADM2914

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 allow each rail to be monitored for both overvoltage (OV) and undervoltage (UV) conditions. The ADM2914 includes a 1 V buffered reference output, REF, that acts as an offset when monitoring a negative voltage.

GENERAL DESCRIPTION

A common active low undervoltage (UV) and overvoltage (OV) pin is shared by each of the monitored voltage rails. 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 Quad UV/OV Positi...
