Maxim Integrated MAX6707LKA+T Microprocessor Supervisor

The MAX6707LKA+T from Maxim Integrated is a robust 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 in systems with +2.5V, +3V, +3.3V, and +5V-powered µPs. This component is particularly suitable for portable electronics, computers, controllers, and intelligent instruments where precise monitoring is crucial for data integrity and system stability.

This supervisory IC ensures that the µP is only operational when the power supply voltage is within acceptable limits. It accomplishes this by providing a reset signal to the µP during power-up, power-down, and brownout conditions. The reset output remains active until the supply voltage reaches the reset threshold and maintains this state for a minimum reset timeout period after the supply voltage exceeds the reset threshold. This ensures a proper system reset and gives the µP enough time to initialize after power disturbances.

The MAX6707LKA+T features a variety of key specifications that make it an excellent choice for system designers. It has a low supply current of only 5.5µA, which is ideal for power-sensitive applications. The reset threshold accuracy is ±2.5% over temperature, ensuring reliable operation under varying conditions. Moreover, the device offers a reset timeout period of 140ms min, providing ample time for system stabilization.

Available in a compact SOT-23 package, the MAX6707LKA+T is designed for space-constrained applications. Its operating temperature range from -40°C to +125°C allows for use in environments with extreme temperature variations. The device is also offered in a lead(Pb)-free/RoHS-compliant package, which is beneficial for environmentally conscious designs that require compliance with current legislation.

In summary, the Maxim Integrated MAX6707LKA+T is a highly reliable and efficient solution for µP system monitoring, offering low power consumption, high accuracy, and a small form factor. Its ease of integration and robust feature set makes it an essential component for maintaining system integrity in a wide range of electronic applications.
