DS1831A - Multisupply Micromonitor

Download the DS1831A datasheet PDF. This datasheet also covers the DS1831 variant, as both devices belong to the same multisupply micromonitor family and are provided as variant models within a single manufacturer datasheet.

General Description

The DS1831 multisupply monitor and reset monitors up to four system voltages: 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 5V input.

Key Features

  • 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 IN5V 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 Watchd.
