Maxim Integrated MAX811JEUS Voltage Monitor

The Maxim Integrated MAX811JEUS is a compact, highly efficient voltage monitor designed to maintain system integrity through precise voltage supervision. Ideal for a variety of applications, including microprocessor systems, computers, controllers, and intelligent instruments, this device ensures that your system operates safely within its voltage parameters.

The MAX811JEUS is a four-pin microprocessor (µP) supervisory circuit used to monitor the power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when monitoring 5V power supplies. Maxim Integrated has designed this component with a +4.63V threshold, which is crucial for systems that require a precise monitoring voltage to ensure proper operation.

This supervisory circuit features a variety of benefits that make it a robust solution for power monitoring. It includes a reset output that remains asserted for a minimum of 140ms after VCC has risen above the reset threshold. This reset function is critical for allowing a proper system restart and recovery after a power failure. Additionally, the MAX811 integrates a manual reset input that enables a manual triggering of the reset signal, providing an extra layer of control for system operators.

The MAX811JEUS comes in a small SOT-143 package, which is perfect for space-constrained applications. It operates over a wide temperature range of -40°C to +85°C, ensuring reliable performance across various environmental conditions. The device also features low supply current, with a typical value of 17µA, which is advantageous for power-sensitive designs.

With its combination of features, the Maxim Integrated MAX811JEUS voltage monitor is an essential component for systems that demand reliable voltage supervision. Its precision, ease of integration, and compact form factor make it a top choice for engineers and designers looking to enhance the safety and stability of their electronic systems.

Whether you are designing a new system or upgrading an existing one, the MAX811JEUS provides the assurance that your system will operate within its intended voltage parameters, protecting your investment and ensuring ongoing operational integrity.
