The DS1813R-5/T is a compact, highly integrated micro-monitor chip designed by Maxim Integrated to enhance the reliability of computer systems. This precision device is engineered to monitor system voltages and provide a controlled microprocessor reset in the event of power failure or out-of-tolerance conditions, ensuring that the system restarts in a known, stable state.

A key feature of the DS1813R-5/T is its ability to assert a reset signal to the microprocessor during power-up, power-down, and brownout conditions. The reset threshold voltage is precisely factory-set at 4.63V, making it suitable for 5V-powered systems. The reset signal remains asserted for a minimum of 350ms after the supply voltage exceeds the reset threshold, providing ample time for the system to stabilize.

This micro-monitor chip is available in a compact SOT-23 package, which is ideal for space-constrained applications. The DS1813R-5/T is also characterized for operation over a wide temperature range, from -40°C to +85°C, allowing it to perform reliably in diverse operating environments.

Maxim Integrated's DS1813R-5/T is an essential component for systems requiring robust power management and reset functions. It helps prevent firmware corruption and other malfunctions that can occur due to unpredictable power supply conditions. As a result, it is widely used in applications such as embedded systems, computers, controllers, and other microprocessor or microcontroller-based equipment.

The device's ease of use, combined with its small footprint and precise voltage monitoring capabilities, makes it an excellent choice for designers looking to improve system reliability and performance. With the DS1813R-5/T, Maxim Integrated continues to demonstrate its commitment to providing innovative, high-quality solutions for the electronics industry.
