DS1708SESA+

Supervisors Overview

The DS1708SESA+ is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input with a threshold of 3.3 V and an overvoltage threshold of 3 V. The device operates within a supply voltage range up to 5.5 V and features a reset delay time of 205 ms. It draws a typical operating current of 60 uA and maintains accuracy within 10%. The component supports active high, active low, and push-pull output configurations without manual reset or watchdog timer functions. It is housed in an SOIC-8 package and operates between -40°C and +85°C.

Supervisors Feature Summary

• Provides power-failure detection capabilities for system monitoring
• Supports configurable active high, active low, and push-pull output types
• Operates with low quiescent current consumption

Supervisors Applications

• Embedded systems requiring voltage supervision
• Portable electronic devices needing power management
• Industrial control circuits with limited power budgets

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm exact threshold voltages and package variations. Confirm RoHS compliance status through manufacturer documentation. Check current availability as distribution channels may indicate restricted supply or discontinuation. Ensure the selected variant matches the required operating temperature range and output configuration for the target application design.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with configurable outputs is required. Compare threshold specifications against other variants in the DS1708S series to match the specific rail voltage being monitored. Consider the SOIC-8 footprint constraints and ensure the 205 ms reset delay aligns with system startup timing requirements. Verify that the absence of a watchdog timer meets the safety standards of the intended application.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroMonitor family, designed for supervising power rails in compact electronic designs. The DS1708SESA+ variant specifically targets applications requiring a 3.3 V threshold with narrow tolerance. It serves as a critical component for ensuring system stability during power transitions and brown-out events in portable and industrial equipment.

Supervisors Replacement Considerations

Consult official substitution guides for equivalent parts within the DS1708S series or compatible MicroMonitor families. Verify pinout compatibility and electrical parameter alignment before replacing.
