Maxim Integrated MAX6356LSUT+T Microprocessor Supervisory Circuit

The MAX6356LSUT+T from Maxim Integrated is a 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 systems with 3.3V power supplies.

This compact supervisory circuit is housed in a space-saving 6-pin SOT-23 package, making it ideal for portable and space-constrained applications. The MAX6356LSUT+T offers a variety of features to ensure system stability, including a reset output during power-up, power-down, and brownout conditions. The reset signal remains asserted for a minimum timeout period after V<sub>CC has risen above the reset threshold, ensuring that the µP is held in reset until conditions are stable for reliable operation.

The device features a factory-trimmed reset threshold suitable for operation with a 3.3V power supply, and the reset timeout period can be set by an external capacitor, allowing designers to customize the reset delay to match specific system requirements. Additionally, the MAX6356LSUT+T offers a manual reset input, providing a simple way to initiate a system reset through an external push-button or other input signal.

With its low supply current of only 1.2µA (typical), the MAX6356LSUT+T is an energy-efficient choice for battery-operated devices. It also includes a debounced manual reset input, which further enhances system stability by filtering out any noise or glitches that could inadvertently trigger a reset.

Overall, the MAX6356LSUT+T is an ideal solution for managing system resets in microprocessor-based systems, offering both high reliability and ease of use. Its combination of features ensures that digital systems operate smoothly by providing a controlled startup and protecting against voltage anomalies, making it a valuable component in a wide range of applications, from consumer electronics to industrial control systems.
