DS1706EUA/T&R

Supervisors Overview

The DS1706EUA/T&R is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input with a threshold of 5 V and features an active low, push-pull output. The device includes a watchdog timer and power-fail detection capabilities. It operates within a supply voltage range up to 5.5 V and maintains accuracy within 10%. The reset delay time is specified at 205 ms, while the quiescent current is 60 uA. The component supports surface mount installation in SOIC-Narrow-8 packaging and functions reliably across a temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides power-fail warning detection functionality
• Features active low push-pull output configuration

Supervisors Applications

• Microprocessor system supervision
• Portable equipment power management
• Battery-powered instrument monitoring

Supervisors Procurement Notes

Verify the specific suffix designation when ordering, as tape and reel packaging may differ from tube quantities. Confirm RoHS compliance status through official documentation prior to integration. Ensure the selected variant matches the required threshold voltage and package type for the target design. Cross-reference manufacturer datasheets for any recent updates regarding pinout or electrical characteristics.

Supervisors Selection Notes

Select this component for applications requiring integrated watchdog and power-fail monitoring in a compact surface-mount package. Evaluate the 5 V threshold against the target supply rail to ensure proper triggering. Consider the 60 uA operating current for battery-sensitive designs. Verify that the SOIC-Narrow-8 footprint aligns with existing board layout constraints and thermal requirements.

Supervisors Part Context

This part belongs to the DS1706 MicroMonitor series, designed for simple reset and power-fail applications. It complements other variants like the DS1706SEUA and DS1706ESA+T&R, offering different package options such as uMAX and SOIC. The series focuses on providing essential supervisory functions with minimal external components for cost-effective system protection.

Supervisors Replacement Considerations

Direct substitutes include DS1706ESA+T&R and DS1706PESA+T&R. Verify compatibility regarding threshold voltage, output polarity, and package dimensions before substitution.
