DS1818R-5/TR Description

Short technical summary and product information.

The DS1818R-5/TR from Analog Devices is a precision voltage monitoring IC that enhances processor operation reliability. It provides automated power-fail detection and ensures a stable restart after power interruptions by maintaining a reset signal for approximately 150ms after VCC returns to tolerance.

Key electrical specifications include a fixed 3.3V reset threshold with available tolerances of 5%, 10%, and 20%. The device operates with a low quiescent current of 35µA maximum. It also features an active-low reset output and an open-drain output with an internal 5.5kΩ pullup resistor.

Designed for commercial and industrial environments, the DS1818R-5/TR operates across a temperature range of -40°C to +85°C. It supports manual reset control via a pushbutton input. The supervisor is available in both TO-92 and SOT-23 package types, suitable for through-hole and surface-mount applications respectively.

This supervisor is ideal for applications requiring precise power supply monitoring and reliable microprocessor management, preventing system resets due to voltage fluctuations or power failures.
