DS1708TESA/T&R

Supervisors Overview

The DS1708TESA/T&R is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 2.63V to 5.5V and features dual threshold voltages at 4.63V and 2.93V. The device includes a fixed reset delay time of 200ms and draws a maximum quiescent current of 10µA. It is housed in an 8-pin SOIC-Narrow package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides independent monitoring for two distinct power rails with dedicated threshold detection
• Generates active-low reset signals upon detecting undervoltage conditions on monitored inputs
• Includes a fixed internal timer to ensure stable power-up sequencing before asserting the reset output

Supervisors Applications

• Dual-rail embedded system power management
• Industrial control unit voltage supervision
• Telecommunications equipment power integrity monitoring

Supervisors Procurement Notes

Verify the specific suffix 'TESA' against official manufacturer documentation, as standard listings typically reference 'SESA'. Confirm RoHS compliance status and lead times directly with authorized distributors due to potential limited availability or obsolescence notices associated with this Maxim Integrated component series.

Supervisors Selection Notes

Select this component when dual-voltage supervision is required without external comparator complexity. Ensure the 4.63V and 2.93V thresholds align with the target system's critical rail limits. Verify that the 200ms reset delay meets the microcontroller's minimum power-on reset requirements.

Supervisors Part Context

This part belongs to the DS1708S MicroMonitor family, designed for reliable power supervision in compact electronic systems. It simplifies design by integrating dual thresholds and reset timing into a single small-outline package, reducing board space compared to discrete solutions.

Supervisors Replacement Considerations

Consult official cross-reference guides for equivalents such as the DS1708SESA variant. Verify pin compatibility and threshold voltage tolerances before substitution.
