DS1708RESA+T&R

Supervisors Overview

The DS1708RESA+T&R is a supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for monitoring voltage levels in electronic systems. It operates within a supply voltage range of 2.8 V to 5.5 V and supports threshold voltages of 3.3 V and 5.0 V. The device features active high, active low, and push-pull output types with a reset delay time of 285 ms. It includes power-fail detection capabilities but lacks manual reset, watchdog timer, and backup battery switch functions. Operating temperatures range from -40°C to +85°C, and it is housed in an SOIC-Narrow-8 package.

Supervisors Feature Summary

• Provides dual threshold voltage supervision for 3.3 V and 5.0 V rails
• Includes power-fail detection to monitor supply integrity
• Offers configurable output states including active high, active low, and push-pull

Supervisors Applications

• Microprocessor system reset circuits
• Portable equipment power management
• Industrial control board supervision

Supervisors Procurement Notes

Verify the specific suffix 'RE' against official datasheets to confirm pinout or functional variations compared to standard variants. Ensure the '+T&R' designation matches the required reel packaging specifications for your assembly line. Cross-reference the manufacturer part number with current availability status as distribution channels may list limited stock or obsolete statuses.

Supervisors Selection Notes

Select this component when dual voltage thresholds are required for simultaneous monitoring of different logic levels. The SOIC-Narrow-8 package suits space-constrained designs. Verify that the 285 ms reset delay aligns with system startup timing requirements. Confirm compatibility with the target operating temperature range of -40°C to +85°C for industrial or commercial environments.
