Maxim Integrated MAX819MESA+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX819MESA+T is a state-of-the-art microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5V-powered circuits.

This supervisory circuit ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The reset output remains operational with VCC as low as 1V. The MAX819MESA+T features an active-high reset, with a reset timeout period of 140ms (min), ensuring that the system has ample time to stabilize before the processor starts executing code.

The device comes in a compact 8-pin SOIC package, making it suitable for space-constrained applications. The MAX819MESA+T operates over a wide temperature range of -40°C to +85°C, ensuring reliable performance in diverse environments. The supply voltage range of 4.5V to 5.5V makes it compatible with standard 5V systems.

Key features of the MAX819MESA+T include:

• Precision Monitoring of 5V Power-Supply Voltages
• Fully Specified Over Temperature
• Active-High Reset Output
• 140ms Min Power-On Reset Pulse Width
• Guaranteed Reset Valid to VCC = 1V
• Low Power Consumption
• 8-Pin SOIC Package

The MAX819MESA+T is ideal for use in computers, controllers, intelligent instruments, critical µP power monitoring, and portable/battery-powered equipment. Its robust feature set and compact design make it an essential component for ensuring system stability and integrity.

For designers and engineers looking for a reliable supervisory solution, the Maxim Integrated MAX819MESA+T offers a blend of performance, ease of integration, and cost-effectiveness that is hard to match in the industry.
