Maxim Integrated DS1812R-5 MicroMonitor Chip

The DS1812R-5 is a versatile micro-monitor chip designed by Maxim Integrated, a renowned leader in the development of innovative analog and mixed-signal products. This compact and efficient component is engineered to enhance the reliability and stability of microprocessor (µP) systems, making it an essential component for a wide range of electronic applications.

At the heart of the DS1812R-5's functionality is its ability to monitor the power supply voltage levels of µP and digital systems. It provides a precise, factory-trimmed threshold that ensures systems are reset to a known state during power-up, power-down, and brownout conditions. The device's active-low reset output guarantees that the µP resets cleanly during power-up or whenever the supply voltage drops below the designated threshold.

The DS1812R-5 is designed to be highly flexible and is available in a small, space-saving SOT-23 package. Its 5V power supply monitoring makes it suitable for a wide range of applications, including embedded systems, computers, controllers, and intelligent instruments. The device's low cost, low power consumption, and ease of use make it a popular choice for designers looking to enhance system integrity without incurring significant overheads.

Key features of the DS1812R-5 include:

• Automatic reset generation during power-up, power-down, and brownout conditions.
• Factory-trimmed V<sub>CC reset threshold for assured monitoring without external adjustments.
• Minimal external components are required for operation, simplifying design and reducing footprint.
• 200ms reset pulse width ensures proper system reset.
• Low-cost solution for system stability and reliability.
• Operates over a wide temperature range, making it suitable for industrial applications.

Whether you are developing mission-critical industrial systems or consumer electronics, the DS1812R-5 offers a reliable and straightforward solution for protecting your system against power supply anomalies. By integrating this micro-monitor chip into your design, you can ensure that your application runs smoothly and consistently, even under challenging power conditions.
