The MAX810J-4.00 is a precision microprocessor (μP) reset circuit developed by Maxim Integrated, a leader in analog and mixed-signal engineering. This device is designed to monitor the supply voltage of μP and digital systems, providing a significant layer of protection and reliability. It is ideal for use in a wide range of applications, including computers, controllers, intelligent instruments, and portable/battery-powered equipment.

Key Features

• Voltage Monitoring: The MAX810J-4.00 monitors the system voltage and asserts a reset signal whenever the VCC supply voltage falls below the factory-set reset threshold of 4.00V, ensuring the proper operation of the μP during power-up, power-down, and brown-out conditions.
• Reset Output: This device provides an active-low reset signal, with an accuracy of ±1.5% at room temperature, which remains asserted for a minimum reset timeout period of 140ms after VCC has risen above the reset threshold. This guarantees the system has sufficient time to stabilize before the processor starts operating.
• Low Power Consumption: With its low supply current of only 17μA (typical), the MAX810J-4.00 is optimized for energy-efficient operations, making it suitable for portable and battery-powered applications.
• Temperature Range: The operating temperature range of the MAX810J-4.00 is from -40°C to +85°C, allowing for reliable operation in a variety of environmental conditions.
• Compact Package: It is available in a compact SOT-23 package, which is ideal for space-constrained applications.

Applications

• Computers and Servers
• Embedded Systems
• Portable and Battery-Powered Equipment
• Intelligent Instruments
• Industrial Controllers

In summary, the MAX810J-4.00 from Maxim Integrated is an essential component for any digital system requiring robust voltage monitoring and reliable reset capabilities. Its precision, low power consumption, and compact form factor make it a versatile choice for engineers and designers looking to enhance system integrity and prevent data corruption due to power irregularities.
