DS1814CR-5-U+

Supervisors Overview

The DS1814CR-5-U+ is a MicroMonitor voltage supervisor manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single input channel with a threshold of 5V and supports 3.3V and 5V systems. The device features active high, active low, and push-pull outputs with a reset delay of 200 ms. Operating from 4.5V to 5.5V, it functions within -40°C to +85°C in an SOT-23-5 package.

Supervisors Feature Summary

• Provides power-fail detection for system supervision
• Offers configurable output polarity options
• Integrates a fixed reset delay timer

Supervisors Applications

• Monitoring 5V logic supply rails
