DS1708TEPA+

Supervisors Overview

The DS1708TEPA+ is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for monitoring power supply voltages. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 3.3 V. The device provides a reset delay time of 205 ms and maintains an accuracy of 5%. It supports active high, active low, and push-pull output types. The component is housed in an 8-DIP package with dimensions of 0.300 inches (7.62 mm) width. It functions without a manual reset or watchdog timer and includes power failure detection capabilities.

Supervisors Feature Summary

• Monitors single input voltage levels for system supervision
• Provides configurable output logic states including push-pull
• Detects power failure conditions automatically

Supervisors Applications

• Microprocessor system supervision
• Power supply voltage monitoring
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the specific package variant, as the TEPA suffix indicates an 8-DIP configuration distinct from SOIC versions. Confirm availability status through authorized distributors, as supply may be limited. Ensure the datasheet matches the exact part number for electrical characteristics. Check RoHS compliance documentation for regulatory requirements. Validate pinout compatibility if replacing existing components on a PCB layout.

Supervisors Selection Notes

Select this component when a simple voltage monitor with a fixed 3.3 V threshold is required. It is suitable for applications needing power failure detection without complex timing features. Consider the DIP package for prototyping or through-hole assembly needs. Evaluate the 5% accuracy against system tolerance requirements. Ensure the 205 ms reset delay aligns with processor startup times.

Supervisors Part Context

This part belongs to the DS1708T series of MicroMonitor devices. These circuits are designed for low-cost voltage supervision in digital systems. The series typically offers various threshold options and package styles. The TEPA variant specifically utilizes a dual-in-line package format. It serves as a fundamental building block for ensuring system stability during power transitions.
