Product Overview

The ADM2914 series 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 over-voltage (OV) and under-voltage (UV) conditions. A common active low under-voltage (UV) and over-voltage (OV) pin is shared by each of the monitored voltage rails. The ADM2914 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. 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 to no greater than 10mA.
  • Quad UV/OV positive/negative supervisor
  • Supervises up to 2 negative rails
  • Adjustable UV and OV input thresholds
  • Open-drain UV and OV reset outputs
  • Adjustable reset timeout with disable option
  • Glitch immunity
  • ±1.5% High threshold accuracy over-temperature
  • 1V Buffered reference output
  • 62µA Supply current
