ADM12914-2ARQZ

ADM12914 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 undervoltage (UV) and overvoltage (OV) conditions with high threshold accuracy of ±0.8%. Common active low undervoltage (UV) and overvoltage (OV) pins are shared by each of the monitored voltage rails. It includes a 1V 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. This device incorporates an internal shunt regulator that enables the device to be used in higher voltage systems. It is used in application such as server supply monitoring, FPGA/DSP core and I/O voltage monitoring, telecommunications equipment, medical equipment etc.
