Maxim Integrated MAX6722UTSVD3+T Microprocessor Supervisory Circuits

The MAX6722UTSVD3+T is a state-of-the-art microprocessor (µP) supervisory circuit designed by Maxim Integrated, a leader in analog and mixed-signal engineering. This compact, highly reliable component is engineered to monitor power supplies in digital systems, ensuring that the µP and other critical system components operate under optimal power conditions. It provides essential protection features for electronic systems, making it an ideal component for a wide range of applications including portable devices, computers, controllers, and intelligent instruments.

One of the key features of the MAX6722UTSVD3+T is its ability to assert a reset signal whenever the VCC supply voltage drops below a preset threshold, ensuring that the µP resets cleanly during power-up, power-down, and brownout conditions. The reset output remains asserted for a minimum timeout period after VCC has risen above the reset threshold, providing the system with a stable interval to recover from an unstable power supply.

The device comes in a tiny, space-saving 6-pin SOT23 package, making it suitable for use in systems where board space is at a premium. Despite its small size, it integrates a debounced manual reset input, allowing for a manual reset capability. This feature is particularly useful for system maintenance or emergency recovery operations.

Another notable characteristic of the MAX6722UTSVD3+T is its low supply current, which is critical for battery-powered applications where power efficiency is paramount. The device's quiescent current is typically just 1.8µA at +3.3V, contributing to extended battery life and reduced power consumption.

Moreover, the supervisory circuit is designed to be highly accurate, with a factory-set reset threshold voltage and a tight reset threshold accuracy of ±1.5% over the entire temperature range of -40°C to +125°C. This precision ensures reliable operation under varying environmental conditions.

Overall, the Maxim Integrated MAX6722UTSVD3+T microprocessor supervisory circuit offers a robust feature set, including low power consumption, high accuracy, and manual reset capability, all within a miniature package. It is a crucial component for any design that requires dependable monitoring of the power supply to safeguard system integrity.
