DS1818R-5+TR Description

Short technical summary and product information.

The DS1818R-5+TR is a supervisor integrated circuit designed by Analog Devices to improve processor operation reliability. It features a temperature-compensated voltage monitor for precise power-fail detection and automatically restarts microprocessors after power failures. The device maintains a reset for approximately 150ms after VCC returns to tolerance, allowing for processor stabilization.

 

Key electrical specifications include a fixed 3.3V reset threshold and an active-low reset output. It also monitors a pushbutton for external override, generating a reset upon release. The supervisor has a low quiescent current of 35µA maximum and includes an internal 5.5kΩ pullup resistor for its open-drain output, saving power and space.

 

This component operates within a commercial and industrial temperature range of -40°C to +85°C. It is available in both TO-92 and SOT-23 package types, supporting through-hole and surface mount applications respectively. The DS1818R-5+TR is suitable for designs requiring robust power supply monitoring and automatic reset capabilities.
