DS1706SESA+

Supervisors Overview

The DS1706SESA+ is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.2 V to 5.5 V and is housed in an SOIC-8 surface-mount package. The device monitors a single input with a threshold voltage of 3.3 V and features an active low, push-pull output. Key functional parameters include a reset delay time of 205 ms, a power-fail detection capability, and a watchdog timer. It lacks manual reset and battery backup switching functions. The component supports an operating temperature range from -40°C to +85°C and consumes 60 µA of quiescent current.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides power-fail detection to signal voltage anomalies
• Features an active low push-pull output driver

Supervisors Applications

• Microprocessor system supervision
• Voltage monitoring in embedded controllers
• Watchdog timing in industrial control units

Supervisors Procurement Notes

Verify the specific suffix 'S' against official datasheets to confirm the exact threshold voltage and accuracy specifications, as variations exist within the DS1706 family. Confirm RoHS compliance status through the manufacturer's documentation. Ensure the SOIC-8 footprint matches your PCB design constraints. Check for obsolescence or limited availability status directly with authorized distributors before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a dedicated watchdog timer and power-fail detection are required alongside voltage supervision. The 3.3 V threshold makes it suitable for 3.3 V logic systems. Consider the 205 ms reset delay for application timing requirements. Compare against the MAX690 series if battery backup switching is needed, or the MAX709 series if higher accuracy is prioritized over integrated watchdog functionality.

Supervisors Part Context

This part belongs to the DS1706 MicroMonitor series, which combines voltage supervision with watchdog timer capabilities. It is designed for applications requiring robust system reset management. The 'S' suffix typically denotes specific electrical characteristics such as threshold voltage and accuracy compared to other variants like the DS1706RESA+. It falls under the broader category of PMIC supervisory circuits provided by Analog Devices.

Supervisors Replacement Considerations

The DS1706RESA+ offers similar functionality but with different threshold and accuracy specifications. The MAX690SESA+ provides comparable supervision but includes battery backup switching. Verify pin compatibility and electrical parameter alignment before substituting.
