DS1813-15/T&R

Supervisors Overview

The DS1813-15/T&R is a single-channel power supply supervisor manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a voltage range of 4.75 V to 5.25 V and features a threshold voltage of 4.13 V. The device provides a low-active reset signal with a minimum timeout of 100 ms. It utilizes an open-drain or open-collector output configuration and is housed in a SOT-23-3 package. The component supports surface mount installation and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides system reset functionality upon detection of under-voltage conditions
• Features a fixed threshold voltage for precise monitoring
• Includes a guaranteed minimum reset timeout period

Supervisors Applications
