The DS1831C multisupply monitor and reset monitors up to four system voltages: 2.5V supply, 3.3V (or 3V) supply, and two additional user configurable voltage monitors.

DS1831 power for internal operation comes from the higher voltage level of the 3.3V input or the 2.5V input.

One of these inputs must be greater than 1V for device operation.

Key Features

  • 2.5V power-on reset.
  • 3.3V power-on reset.
  • Two referenced comparators with separate outputs for monitoring additional supplies.
  • Internal power is drawn from higher of either the IN2.5V input or the IN3.3V input.
