Maxim Integrated's MAX811LEUS+T Microprocessor Voltage Monitor

The MAX811LEUS+T is a compact, highly efficient voltage monitor designed by Maxim Integrated to ensure the reliable operation of microprocessors (µPs) and other voltage-sensitive devices. This component provides essential monitoring functionality by triggering a reset signal whenever the monitored voltage falls below a preset threshold, thus safeguarding the system against power failures, brownouts, and any other voltage-related issues that could lead to data corruption or device malfunction.

Featuring a 4-pin SOT-143 package, the MAX811LEUS+T is tailored for space-constrained applications, offering a minimal footprint without compromising on performance. It is particularly well-suited for portable devices, such as laptops and smartphones, as well as for more complex systems like networking equipment and servers where consistent and reliable operation is critical.

The device operates over a wide voltage range and has a low supply current, making it an energy-efficient choice for battery-operated applications. Its precision voltage monitoring capability ensures that systems are reset to a known state in the event of a power issue. This is especially important in systems where data integrity and uptime are paramount.

Additionally, the MAX811LEUS+T features an active-low reset output, which remains asserted for a minimum of 140ms after the voltage level has returned to an acceptable range. This ensures that the system has ample time to stabilize before normal operation resumes. The device also includes a manual reset feature, allowing for a system reset to be triggered externally, which can be useful for system maintenance and troubleshooting.

With its robust design, the MAX811LEUS+T operates across a broad temperature range, making it suitable for industrial applications that may experience extreme environmental conditions. Its integration into a system is straightforward, requiring minimal external components, which simplifies the design process and accelerates time-to-market for product developers.

In conclusion, the MAX811LEUS+T from Maxim Integrated is a reliable and efficient solution for voltage monitoring in critical applications, ensuring that electronic systems remain operational and secure in the face of unpredictable power conditions.
