DS1814CR-5-U+ Description

Short technical summary and product information.

The Analog Devices DS1814CR-5-U+ is a 5V MicroMonitor designed to monitor critical conditions for microprocessors, including power supply status, software execution, and external override. It features a precision temperature-compensated reference and comparator circuit to monitor VCC. When an out-of-tolerance condition occurs, an internal power-fail signal forces the reset output to an active state. The reset signal is held active for a minimum of 140ms after VCC returns to tolerance, allowing the power supply and processor to stabilize.

 

This device offers an operating voltage of 4.625V and monitors a single voltage rail. The reset output can be active high or active low. It is housed in a compact SOT-23-5 package, suitable for surface mounting. The operating temperature range is -40°C to +85°C, making it suitable for industrial applications. The DS1814CR-5-U+ eliminates the need for discrete components in power monitoring and reset circuitry.

 

Key features include a reset timeout of 140ms minimum and a push-pull output configuration. The device is pin-compatible with MAX823/24/25 products. Its design helps halt and restart microprocessors during power transients and automatically restarts them after power failure.
