DS1817-20+ Description

Short technical summary and product information.

The DS1817-20+ from Analog Devices (formerly Maxim Integrated) is an EconoReset supervisor IC. It automatically restarts a microprocessor after a power failure, maintaining reset for approximately 150 ms after VCC returns to an in-tolerance condition. This device reduces the need for discrete components by providing a precision temperature-compensated voltage reference and voltage sensor.

 

Key electrical specifications include a 2.55V threshold voltage and an active high, push-pull output. The operating temperature range is -40°C to +85°C. The DS1817-20+ is available in a low-cost TO-92-3 package, suitable for through-hole mounting.

 

This supervisor is designed to monitor power supply status and warn a processor-based system of impending power failure. On power-up, the reset signal is kept active for approximately 150 ms after the power supply has reached the selected tolerance, allowing for system stabilization.
