Maxim Integrated MAX6367PKA23+T Supervisory Circuit

The MAX6367PKA23+T is a highly reliable supervisory circuit developed by Maxim Integrated, designed to monitor power supplies in microprocessor systems, providing a significant layer of protection and stability. This compact and efficient component ensures that your system operates correctly by monitoring the power supply voltage and maintaining a reset signal to the microprocessor until stable operating conditions are met.

Encased in a small SOT-23 package, the MAX6367PKA23+T supervisory circuit offers a precise factory-set reset threshold voltage of 2.32V, tailored for 2.5V powered circuits. It is an ideal solution for systems that require a precise and reliable monitoring mechanism to prevent data corruption and ensure proper system boot-up. The low supply current of only 1.2µA (typ) makes it an energy-efficient choice for battery-operated devices.

The device features a manual reset input, which provides a direct way to initiate a system reset. This can be particularly useful for troubleshooting or when a manual system restart is necessary. The reset output is push-pull, which eliminates the need for an external pull-up resistor and simplifies the circuit design. The MAX6367PKA23+T holds the microprocessor in the reset state for a minimum of 140ms after the supply voltage exceeds the reset threshold, ensuring the system has ample time to stabilize.

With its wide operating temperature range of -40°C to +125°C, the MAX6367PKA23+T is versatile and can perform reliably in various environmental conditions, making it suitable for industrial and automotive applications. Its built-in features, such as the debounce input, ensure that the reset signal is clean and free of glitches, which is critical for maintaining system integrity.

Maxim Integrated's commitment to quality and reliability is evident in the MAX6367PKA23+T supervisory circuit. It is a robust choice for designers looking to add a level of protection to their microprocessor-based systems, ensuring that devices operate as intended even in the face of power supply irregularities.

Overall, the MAX6367PKA23+T is a testament to Maxim Integrated's reputation for delivering high-performance, reliable integrated circuits that meet the stringent demands of modern electronic systems.
