DS1706RESA/T&R

Supervisors Overview

The DS1706RESA/T&R is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and monitors a single input with a threshold voltage of 3.3 V. The device features an active low, push-pull output and includes a watchdog timer. It provides power-fail detection and has a reset delay time of 205 ms. The accuracy is specified at 20%. Operating temperatures range from -40°C to +85°C, and the quiescent current is 60 µA. It is housed in an SOIC-8 package.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability
• Power-fail detection capability
• Active low push-pull output configuration

Supervisors Applications

• Voltage monitoring in embedded systems
• Supervisory circuits for microprocessors
• System reset generation

Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm tape-and-reel packaging versus tube packaging, as datasheets may list variations. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the operating temperature range meets application requirements. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-input voltage monitor with integrated watchdog functionality is required. The 3.3 V threshold suits standard logic levels. Consider the 20% accuracy specification against tighter tolerance needs. Verify that the SOIC-8 package fits the PCB layout constraints. Compare quiescent current consumption against battery life requirements if applicable.

Supervisors Part Context

This part belongs to the DS1706R series of MicroMonitor devices. These are designed for low-voltage digital systems requiring reliable supervision. The series typically offers various threshold voltages and packages. The RESA variant specifically denotes the SOIC-8 surface-mount package option within this family.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the DS1706 family. Verify equivalent threshold voltages and output types. Ensure replacement parts support the same watchdog and power-fail features.
