Maxim Integrated DS1816R-5 MicroMonitor Chip

The Maxim Integrated DS1816R-5 is a highly reliable, compact microprocessor supervisory circuit designed to monitor the power supplies in microprocessor and digital systems. It provides a precise way to monitor power supply functionality, ensuring that your system is operating within safe parameters. This supervisory circuit is an essential component for any system requiring a stable and reliable operation, especially in critical applications where data integrity and system uptime are paramount.

The DS1816R-5 offers several key features that make it an indispensable part of your digital system. It has a preset threshold voltage of 4.63V, which is specifically tailored for 5V power supplies. When the power supply voltage drops below this threshold, the DS1816R-5 generates a reset signal, which remains asserted until the supply voltage returns to an acceptable level and a proper power-on reset delay has passed. This ensures that the microprocessor restarts in a known state, preventing software execution errors and potential hardware damage.

With its compact SOT-23 package, the DS1816R-5 is ideal for space-constrained applications. It also features a low-power consumption design, making it suitable for portable and battery-operated devices. The device is equipped with an active-low reset output, which is guaranteed to be in the correct state for V_CC down to 1.0V, providing additional security for low-voltage operations.

Another critical feature of the DS1816R-5 is its debounced manual reset input. This allows for a manual override of the automatic reset, giving system operators direct control over the reset process when necessary. This manual reset capability can be invaluable during system troubleshooting and maintenance.

In summary, the Maxim Integrated DS1816R-5 is a robust, versatile microprocessor supervisory circuit that offers precise voltage monitoring, low power consumption, and manual reset features. It is an ideal solution for maintaining the integrity and reliability of 5V-powered systems, from complex servers to portable electronic devices.
