DS1705ESA

Supervisors Overview

The DS1705ESA+ is a MicroMonitor supervisory circuit manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 5 V with 4.75 V overvoltage detection. The device provides active low, push-pull output and includes a built-in watchdog timer. It offers a reset delay time of 205 ms and maintains an accuracy of 5%. Designed for surface mount installation in an SOIC-8 package, it supports power failure detection without manual reset or battery backup switching capabilities.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability monitoring
• Active low push-pull output configuration
• Power failure detection capability
• Fixed threshold voltage supervision

Supervisors Applications

• Voltage monitoring in embedded systems
• Supervision of 3.3V and 5.0V logic circuits
• Watchdog timer implementation in microprocessor systems

Supervisors Procurement Notes

Verify the exact part number suffix against official datasheets to ensure correct package and temperature rating compatibility. Confirm RoHS compliance status through manufacturer documentation before integration. Check current availability as distribution channels may indicate limited stock or discontinuation status. Validate that the SOIC-8 footprint matches your PCB design requirements.

Supervisors Selection Notes

Select this component when a fixed 5 V threshold is required for single-input voltage monitoring. Consider the 60 uA operating current for low-power applications. Ensure the -40 C to +85 C operating temperature range meets environmental specifications. Verify that the absence of manual reset and chip enable signals aligns with the system control architecture.
