Maxim Integrated MAX6722UTSDD3+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX6722UTSDD3+T is a highly reliable and robust microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in system monitoring applications.

This supervisory circuit is particularly suited for portable and space-constrained applications due to its small 6-pin SOT-23 package. It ensures that the microprocessor is reset to a known state during power-up, power-down, or brownout conditions. The MAX6722UTSDD3+T asserts a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold.

Key features of the MAX6722UTSDD3+T include:

• Factory-trimmed VCC reset threshold voltages suitable for a variety of applications.
• Low 1.2µA supply current, which is ideal for battery-powered equipment.
• Guaranteed reset valid to VCC = 1V, ensuring reliable operation during low voltage conditions.
• Immunity to short VCC transients, preventing false resets and system malfunctions.
• Push-pull RESET output that provides active-high or active-low signals depending on the needs of the system.

The device's operation is guaranteed over the full temperature range of -40°C to +85°C, making it versatile for use in various environmental conditions. The MAX6722UTSDD3+T is also lead-free and RoHS compliant, ensuring adherence to current environmental standards and regulations for electronic components.

Maxim Integrated's commitment to high-quality and reliability makes the MAX6722UTSDD3+T an excellent choice for critical system monitoring roles in complex electronics. Whether used in consumer electronics, networking, computers, or portable devices, this supervisory circuit provides the necessary protection and monitoring to ensure stable and reliable operation of the microprocessor and associated digital systems.
