Maxim Integrated DS1706ESA+ Overview

The DS1706ESA+ is a high-precision microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It is an essential component for ensuring system reliability and robustness, particularly in applications where data integrity and system uptime are critical. This device provides a multitude of features including power-on reset control, watchdog timer, and a precision temperature-compensated reference voltage source.

Key Features

• Power-Supply Monitoring: The DS1706ESA+ ensures that the system's microprocessor is fully reset during power-up, power-down, and brownout conditions. It monitors the power supply voltage and keeps the µP in reset until that voltage reaches a stable and acceptable level for system operation.
• Watchdog Timer: The integrated watchdog timer keeps systems running smoothly by forcing a system reset if the µP fails to strobe within a preset timeout period. This feature is crucial for systems that cannot afford to hang or become unresponsive.
• Manual Reset Input: A manual reset input allows for an external trigger to reset the system, providing an additional layer of control for system operators or during debugging processes.
• Low Power Consumption: With its low power consumption, the DS1706ESA+ is an excellent choice for portable and battery-operated applications, ensuring minimal impact on overall system power reserves.
• High Accuracy: The device features a precision temperature-compensated voltage reference which maintains tight regulation over the full temperature range, a critical parameter for sensitive electronic systems.

Applications

The DS1706ESA+ is versatile and can be used in a variety of applications, including:

• Computers and servers
• Embedded systems
• Industrial controllers
• Portable/battery-powered equipment

Technical Specifications

Encased in an 8-pin SO package, the DS1706ESA+ operates over a wide voltage range and is characterized for operation over the full industrial temperature range. It is available in both commercial and industrial temperature ranges, making it suitable for a broad spectrum of environments and applications.

With its combination of features, the DS1706ESA+ from Maxim Integrated is a reliable solution for system monitoring and provides an essential safeguard against power-related system failures.
