DS1831S+

Supervisors Overview

The DS1831S+ is a MicroMonitor voltage supervisor manufactured by Analog Devices Inc./Maxim Integrated. It monitors up to four power supply rails and provides reset signals for system protection. The device operates within a supply voltage range of 2.7V to 5.5V and features an active low, open-drain output. It includes manual reset functionality and offers configurable reset delay times of 10ms, 100ms, or 1,000ms. The component is housed in a 16-SOIC surface-mount package and supports threshold voltages including fixed 3.3V and 5V options alongside adjustable settings.
