DS1816R-5-U

Supervisors Overview

The DS1816R-5-U is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1V to 5.5V and features a fixed threshold voltage of 3.06V. The device provides a low-active reset signal with an open-drain or open-collector output configuration. It includes a minimum reset timeout of 100ms to ensure stable power-up sequencing. The component is housed in a surface-mount SOT-23-3 package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides simple power-on reset functionality for microprocessor systems
• Features an open-drain or open-collector active-low reset output
• Includes a guaranteed minimum reset timeout period for reliable startup

Supervisors Applications

• Microcontroller power supply monitoring
