DS1708SEUA

Supervisors Overview

The DS1708SEUA+ is a MicroMonitor voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 2.93 V. The device provides a single monitored input with push-pull output capabilities, supporting both active high and active low configurations. It includes a manual reset function but lacks a watchdog timer or battery backup switch. The reset delay time is specified at a minimum of 130 ms. Designed for surface mount installation in an 8-uMAX/uSOP package, it functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed 2.93 V threshold for monitoring power rails.
• Features configurable push-pull outputs that support both active high and active low logic states.
• Includes a manual reset input pin allowing external control over the system reset state.
• Delivers guaranteed reset timing with a minimum delay of 130 ms to ensure stable power-up sequences.

Supervisors Applications

• Monitoring microprocessor power supply voltages in embedded systems
• Providing power-fail warnings for critical data protection circuits
• Ensuring reliable startup sequences in industrial control equipment

Supervisors Procurement Notes

Verify the exact suffix against official datasheets, as variations may indicate different thermal grades or packaging formats. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as historical batches may differ. Check current availability through official channels, as lead times can vary significantly due to supply chain constraints. Ensure the selected variant matches the required operating temperature range and package dimensions for your specific PCB layout.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is appropriate for the target power rail. Consider the manual reset feature if external reset control is required by the system design. Verify that the 8-uMAX package fits the available board space. Compare against other MicroMonitor variants if adjustable thresholds or additional features like watchdog timers are needed for more complex applications.

Supervisors Part Context

The DS1708SEUA+ belongs to the Maxim Integrated MicroMonitor family, designed for simple yet effective voltage supervision. This series focuses on providing essential reset functionality without complex programming requirements. The uMAX package offers a compact solution for space-constrained designs while maintaining robust performance standards typical of industrial-grade analog devices.

Supervisors Replacement Considerations

Consult official cross-reference lists for direct replacements. Ensure any substitute maintains the 2.93 V threshold and 8-pin uMAX footprint. Verify compatibility with existing circuitry regarding output drive strength and reset timing characteristics before implementation.
