Maxim Integrated's MAX6734KAZWD3+T Microprocessor Supervisory Circuit

The MAX6734KAZWD3+T is a highly reliable microprocessor (µP) supervisory circuit designed by Maxim Integrated 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 in system monitoring applications. This component is ideal for portable, networking, telecommunications, and other applications where efficient power management and system reliability are essential.

This supervisory circuit offers several key features that make it stand out. It includes a reset output that remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, ensuring that the µP starts up in a known state. The reset threshold voltage for the MAX6734KAZWD3+T is factory-set and can detect a variety of voltage levels, making it suitable for monitoring 3V, 3.3V, and 5V power supplies.

Additionally, the MAX6734KAZWD3+T features a manual reset input that allows for a very low supply current of 1.6µA, making it energy-efficient for battery-powered applications. It is also equipped with a watchdog timer that helps to ensure that if the µP or software fails, the system can recover through a reset.

Another advantage of the MAX6734KAZWD3+T is its compact package. It is available in a small 5-pin SOT23 package, which is suitable for space-constrained applications. The operating temperature range of -40°C to +125°C allows for its use in environments that experience extreme temperatures.

For ease of integration, the MAX6734KAZWD3+T is fully specified over the automotive temperature range and is available in a lead(Pb)-free, RoHS-compliant package. This makes it not only a versatile choice for a wide range of applications but also compliant with current environmental standards for electronic components.

In summary, Maxim Integrated's MAX6734KAZWD3+T microprocessor supervisory circuit is a reliable, low-power solution that enhances system stability by providing crucial monitoring functions. Its ease of use, combined with its robust feature set, makes it an excellent choice for designers looking to improve system reliability without increasing complexity.
