The Maxim Integrated DS1832 MicroMonitor Chip is a compact, highly integrated solution designed to provide essential monitoring functions for microprocessor (µP) systems. This innovative chip helps to ensure the reliable operation of the system by monitoring the power supply and providing a reset signal to the µP during power-up, power-down, and brownout conditions.

Key Features

• Power Supply Monitoring: The DS1832 constantly checks the system's power supply voltage. It generates a reset signal to the µP if it detects an out-of-tolerance condition, ensuring the system operates within safe voltage levels.
• Programmable Reset Signal: The reset output is guaranteed to remain in the active state for a minimum of 150ms after the power supply has returned to an acceptable level. This provides the µP ample time to initialize and stabilize.
• Manual Reset Input: The device includes a manual reset input that allows for an external trigger to reset the system, offering an additional layer of control.
• Compact Sizing: Housed in a small 8-pin package, the DS1832 is suitable for space-constrained applications where board real estate is at a premium.

Applications

The DS1832 is versatile and can be used in a variety of applications, including:

• Computers and servers
• Embedded systems
• Communication equipment
• Industrial controllers

Technical Specifications

The DS1832 operates over a wide voltage range and has the following technical specifications:

• Supply Voltage Range: 2.88V to 5.5V
• Active-Low Reset Output
• Temperature Range: -40°C to +85°C

With its robust feature set, the Maxim Integrated DS1832 MicroMonitor is an essential component for any system requiring reliable µP supervision. By safeguarding against power supply irregularities and providing a controlled reset mechanism, it enhances the overall stability and performance of electronic systems.
