DS1708SEUA+

Supervisors Overview

The DS1708SEUA+ is a MicroMonitor voltage supervisor from Analog Devices Inc./Maxim Integrated, housed in an 8-uMAX/uSOP surface-mount package. It monitors a single input with a threshold voltage of 2.93V and features push-pull/totem pole outputs supporting active high or low configurations. The device includes power-fail detection, operates within a supply range up to 5.5V, and draws 60 uA. It provides a minimum reset timeout of 130ms, maintains accuracy within specified limits, and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrated power-fail warning capability for upstream voltage monitoring
• Configurable output polarity supporting both active high and active low signals
• Low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

• CPU supervisor voltage sense inputs
• Monitoring upstream voltage supplies for power-fail warnings
• Simple reset and power-on reset circuits

Supervisors Procurement Notes

Verify the specific suffix SEUA against official datasheets to confirm the 2.93V threshold and 8-uMAX package variant. Confirm RoHS compliance status as documentation may vary by production batch. Check manufacturer lifecycle status for availability constraints. Ensure pinout compatibility with existing PCB layouts before integration.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is required for system supervision. The 8-uMAX package offers space efficiency for compact designs. Consider the configurable output polarity for interface flexibility with various logic families. Verify that the 60 uA operating current meets system power budget requirements.

Supervisors Part Context

Part of the Maxim Integrated MicroMonitor family designed for supervising critical voltage rails in embedded systems. The series provides reliable reset generation and power-fail indications without requiring external components. This specific model targets applications needing precise monitoring of lower voltage levels compared to standard 5V supervisors.

Supervisors Replacement Considerations

DS1706SEUA+ is listed as a direct substitute.
