DS1705ESA+

Supervisors Overview

The DS1705ESA+ is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It features a single voltage monitor input with a threshold of 5 V and an overvoltage threshold of 4.75 V. The device operates within a supply voltage range of 1.2 V to 5.5 V, consuming 60 uA of working current. It provides an active low, push-pull output with a reset delay time of 205 ms. Accuracy is specified at 5%. The component includes a watchdog timer but lacks manual reset or battery backup switch functions. It is housed in an SOIC-8 package for surface mount installation and supports power failure detection.

Supervisors Feature Summary

• Integrates a watchdog timer for system stability monitoring
• Detects power failure conditions automatically
• Provides active low push-pull reset output signal

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset generation
• Industrial control circuit monitoring

Supervisors Procurement Notes

Verify the specific suffix and manufacturer designation against official Analog Devices documentation to confirm exact electrical characteristics and pinout compatibility. Ensure the source document explicitly lists the DS1705ESA+ part number to avoid confusion with similar variants in the MicroMonitor family. Cross-reference the RoHS compliance status and environmental certifications directly from the manufacturer's datasheet before procurement.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with integrated watchdog functionality is required for 5 V systems. Consider the 5% accuracy specification and 205 ms reset delay for timing-sensitive applications. Evaluate the SOIC-8 package constraints and operating temperature range of -40 C to +85 C against environmental requirements. Confirm that the absence of manual reset and battery backup features aligns with the design architecture.
