DS1814AR-5+T&R

Supervisors Overview

The DS1814AR-5+T&R is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single input voltage with a threshold of 5 V and features a push-pull output capable of active high or active low states. The device includes power-fail detection and operates within a temperature range of -40°C to +85°C. It draws a typical supply current of 15 µA and has a reset delay time of 200 ms. The component is housed in an SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Integrated power-fail detection for monitoring supply integrity
• Configurable push-pull output supporting active high or active low logic states
• Low quiescent current consumption suitable for battery-operated systems
