Maxim Integrated's MAX810LEUR+T - Microprocessor Reset Circuit

The MAX810LEUR+T is a precision microprocessor (µP) reset circuit device from Maxim Integrated that ensures reliable operation of microprocessor systems by monitoring the power supply. It is designed to provide a quick and assertive response to any situation where the power supply falls below a predetermined threshold, effectively safeguarding the system from erratic behavior due to unexpected brown-outs or power dips.

This compact and efficient component is housed in a small 3-pin SOT-23 package, making it an ideal choice for space-constrained applications. The MAX810LEUR+T operates with a nominal threshold voltage of 4.63V, tailored for systems that run on a 5V power supply. When the voltage drops below this threshold, the device actively pulls down the reset output, ensuring that the µP remains in a reset state until stable conditions are restored.

One of the key features of the MAX810LEUR+T is its ability to assert a reset signal for a minimum of 140ms (milliseconds) after the supply voltage exceeds the reset threshold. This built-in delay provides ample time for the power supply and µP to stabilize before normal operation resumes, thereby preventing any potential malfunctions due to transient conditions.

Additional characteristics of the device include a low supply current of just 17µA (microamperes), which is beneficial for power-sensitive designs. The MAX810LEUR+T is also designed to ignore fast transients on the VCC line, enhancing the stability of the reset function in noisy environments.

Maxim Integrated's MAX810LEUR+T is versatile and can be used in a wide array of applications ranging from computers and controllers to portable/battery-operated equipment. Its reliability and precision make it an essential component for ensuring the integrity of electronic systems, where consistent operation and protection from power supply anomalies are paramount.

Overall, the MAX810LEUR+T from Maxim Integrated is a robust, reliable, and precise solution for managing µP reset functions, contributing to the overall stability and performance of sophisticated electronic systems.
