DS1705ESA+T&R

Supervisors Overview

The DS1705ESA+T&R is a supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an SOIC-8 surface-mount package. It operates within a supply voltage range of 1.2 V to 5.5 V and monitors a single input with a threshold voltage of 5 V. The device features a watchdog timer, active low push-pull output, and a reset delay time of 205 ms. It includes power failure detection but lacks manual reset and battery backup switching capabilities. Operating accuracy is specified at 5%, with a quiescent current of 60 uA and an overvoltage threshold of 4.75 V.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides power failure detection capability
• Features active low push-pull output configuration

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microcontroller reset circuits
• Industrial control units

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm tape-and-reel packaging availability. Confirm RoHS compliance status through authorized channels. Ensure the component matches the exact part number specifications before integration into designs.

Supervisors Selection Notes

Select this component when a single-input voltage monitor with integrated watchdog functionality is required. Consider the 1.2 V minimum operating voltage for low-power applications. Verify that the SOIC-8 package fits the board layout constraints and that the 205 ms reset delay meets system timing requirements.
