Product Overview: MAX6864UK31D3S+ from Maxim Integrated

The MAX6864UK31D3S+ is a high-quality microprocessor (µP) supervisory circuit that offers an efficient solution for monitoring power supplies in µP and digital systems. Manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering, this device provides a precise, low-power method to monitor system voltages, ensuring that the systems it protects are operating under optimal power conditions.

With its compact SOT23-5 package, the MAX6864UK31D3S+ is designed to conserve space on densely packed circuit boards, making it an ideal choice for space-constrained applications. It features a factory-trimmed reset threshold voltage of 3.1V, which is suitable for managing 3.3V powered systems. When the monitored voltage falls below this threshold, the device asserts a reset signal to prevent the system from operating under inadequate power conditions, which could lead to erratic behavior or damage.

The reset output of the MAX6864UK31D3S+ is of the active-low, open-drain type, which allows for simple interfacing with other logic components. Additionally, it has an internal debounce circuitry that ensures the reset output will remain in the active state for a minimum of 140ms after V_CC has risen above the reset threshold. This built-in delay provides ample time for the power supply and the µP to stabilize before normal operation resumes.

One of the key features of the MAX6864UK31D3S+ is its low supply current, making it particularly well-suited for battery-operated devices where power efficiency is crucial. The device also supports a wide operating temperature range of -40°C to +125°C, enabling its use in diverse environmental conditions, from industrial to automotive applications.

For designers and engineers looking to enhance the reliability and performance of their systems, the MAX6864UK31D3S+ offers a robust solution. Its ease of implementation along with the reputation of Maxim Integrated for producing high-quality integrated circuits makes this supervisory circuit a reliable choice for system power monitoring tasks.
