Maxim Integrated MAX6804US46D2+T Microprocessor Reset Circuit

The Maxim Integrated MAX6804US46D2+T is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides a significant level of protection for your sensitive microprocessor-based systems, ensuring that they operate smoothly and consistently. This device is particularly adept at maintaining system integrity during power-up, power-down, and brown-out conditions.

With its precision factory-set V<sub>CC reset threshold voltage, the MAX6804US46D2+T ensures that the µP resets from 4.625V to 4.675V, which is ideal for systems that operate at 5V power supply levels. The reset output remains asserted for a minimum timeout period of 140ms after V<sub>CC has risen above the reset threshold level, providing ample time for the system to stabilize.

This supervisory circuit comes in a compact, space-saving SOT-143 package, making it suitable for use in systems where board space is at a premium. Its low supply current of 6µA (typical) ensures minimal power consumption, contributing to the energy efficiency of the overall system. This device is particularly useful in battery-powered equipment due to its low power requirements.

Key features of the MAX6804US46D2+T include:

• Precision V<sub>CC monitoring of 5V power supplies
• Factory-set reset threshold voltage for reliable operation
• Minimum 140ms reset timeout period
• Low supply current of 6µA (typical)
• Compact SOT-143 package
• Operating temperature range: -40°C to +125°C

This product is offered in tape and reel packaging, denoted by the "+T" in the part number, which facilitates automated assembly processes, making it an excellent choice for high-volume production.

Whether you are designing complex computing systems, portable devices, or industrial equipment, the Maxim Integrated MAX6804US46D2+T provides the necessary protection for your microprocessors, ensuring that your devices operate reliably and effectively under a variety of conditions.
