DS1831D - 3.3V/2.5V Multisupply MicroMonitor

Download the DS1831D datasheet PDF. This datasheet also covers the DS1831C variant, as both devices belong to the same 3.3v/2.5v multisupply micromonitor family and are provided as variant models within a single manufacturer datasheet.

Description

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.

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.
  • Excellent for systems designed to operate with multiple power supplies.
  • Asserts resets during power transients.
  • Pushbutton reset input for system override.
  • Maintains reset for user configurable times of 10ms, 100ms, or 1s.
  • Watchdog timer for s.
