The Maxim Integrated DS1708SESA is a compact, high-precision micro-monitor chip designed to safeguard system integrity during power cycling and brownout conditions. This essential component monitors the system voltage and helps prevent data corruption by providing a reset signal to the host processor during power-up, power-down, and brownout conditions.

Key Features

• Voltage Monitoring: The DS1708SESA actively monitors the VCC for undervoltage conditions at the selected threshold. Once the VCC falls below the minimum VTRIP value, the reset signal is asserted to prevent system instability.
• Reset Signal: The reset output remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, ensuring the system has stabilized before normal operation resumes.
• Low Power Consumption: With its low power consumption, the DS1708SESA is ideal for power-sensitive applications, allowing for more efficient system design.
• High Accuracy: This micro-monitor chip provides high threshold accuracy (±2.5%) which is crucial for reliable system performance.
• Manual Reset: An additional feature is the manual reset input that allows for a system reset to be triggered with an external push-button or logic signal.

Applications

The DS1708SESA is versatile and can be used in a wide range of applications, including:

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

Package and Availability

The DS1708SESA is available in an 8-pin SO (150 mils) package, which is suitable for surface-mount technology, making it easy to integrate into various circuit designs. The chip's industry-standard footprint ensures compatibility with many PCB layouts.

As an essential component for system stability and data integrity, the Maxim Integrated DS1708SESA MicroMonitor Chip is a reliable choice for designers and engineers looking to enhance the resilience and performance of their electronic systems.
