DS1706EPA

Supervisors Overview

The DS1706EPA+ is a supervisory circuit from the MicroMonitor series, designed to monitor power supply conditions for microprocessors. It operates within a voltage range of 1.2 V to 5.5 V and features a threshold voltage of 5 V with 10% accuracy. The device includes a watchdog timer and detects power failures, generating an active low reset signal after a delay of 205 ms. It supports through-hole mounting in an 8-pin PDIP package and functions across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors power supply status and generates reset signals upon detecting out-of-tolerance conditions.
• Integrates a watchdog timer to ensure software execution integrity.
• Detects power failure events to force the reset line to an active state during voltage degradation.

Supervisors Applications

• Microprocessor system supervision
• Power-on reset generation
• Watchdog timer implementation

Supervisors Procurement Notes

Verify component authenticity due to obsolete status. Confirm package type matches design requirements. Check RoHS compliance documentation. Validate operating temperature range suitability. Ensure substitute availability if discontinuation impacts production schedules.

Supervisors Selection Notes

Select this part for systems requiring 5V monitoring with manual reset capabilities absent. Consider the PDIP-8 package for through-hole assembly needs. Evaluate the 205 ms reset delay against processor stabilization times. Assess the 60 uA supply current for power efficiency constraints.

Supervisors Part Context

This component belongs to the DS1706 family of voltage monitors. It serves as a dedicated supervisory circuit for digital systems. The device replaces discrete components for reset generation. It offers pin compatibility with similar legacy parts in standard packages.

Supervisors Replacement Considerations

Public confirmed substitutes include DS1706ESA+ and DS1706PEPA+. Verify package differences such as SOIC or narrow DIP options. Check for variations in reset delay times and manual reset features. Ensure electrical parameters match system requirements before substitution.
