DS1708TESA+

Supervisors Overview

The DS1708TESA+ is a single-input voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 3.3 V with an accuracy of 5%. The device provides active high, active low, or push-pull outputs and includes power-fail detection capabilities. It lacks manual reset, watchdog timer, battery backup switch, and chip enable functions. The reset delay time is specified at 205 ms, while the overvoltage threshold is set at 3.15 V. Operating current is 60 uA, and it supports an industrial temperature range from -40 C to +85 C. The component is housed in an SOIC-8 package.

Supervisors Feature Summary

• Provides precise monitoring of a single input voltage line with defined threshold levels for system supervision.
• Offers flexible output configurations including active high, active low, and push-pull modes to interface with various logic families.
• Integrates power-fail detection functionality to signal voltage anomalies without requiring external components.

Supervisors Applications

• Monitoring 3.3 V and 5.0 V microprocessor power supplies
• Supervisory circuits for embedded systems requiring voltage validation
• Industrial control applications operating within extended temperature ranges

Supervisors Procurement Notes

Verify availability status as distribution channels may indicate limited supply or discontinuation. Confirm RoHS compliance details through official manufacturer documentation prior to procurement. Ensure the specific suffix matches design requirements for package and performance characteristics. Cross-reference ordering numbers with authorized distributors to validate authenticity and sourcing channels.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with 5% accuracy is required for 3.3 V systems. Consider the SOIC-8 package constraints and push-pull output flexibility. Evaluate the 205 ms reset delay against system startup timing requirements. Verify that the absence of a watchdog timer aligns with the overall system architecture design.

Supervisors Part Context

The DS1708TESA+ belongs to the DS1708T series of MicroMonitor devices. It is part of the broader PMIC category focusing on supervisory circuits. This specific variant distinguishes itself through its 5% accuracy rating and 3.15 V overvoltage threshold, differentiating it from other series members like the DS1708S which offers different accuracy specifications.
