Maxim Integrated MAX6320PUK46BY/V+T Microprocessor Supervisory Circuit

The MAX6320PUK46BY/V+T is a highly reliable microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a trusted name in the development of advanced integrated circuits. This precision voltage-monitoring device is tailored to maintain system integrity by monitoring the power supply voltage of digital systems. It is a vital component for applications that require a high level of operational stability and accuracy.

With its compact SOT-23 package, the MAX6320PUK46BY/V+T is engineered to occupy minimal space on a PCB, making it an ideal choice for space-constrained applications. It operates over a wide temperature range, ensuring consistent performance in diverse operating conditions.

The device features a preset threshold voltage of 4.63V, which is monitored with a tight accuracy of ±1.5% over the entire operating temperature range of -40°C to +125°C. This precision ensures that the µP and other critical components are protected from undervoltage conditions that could lead to system failure or data corruption.

One of the key attributes of the MAX6320PUK46BY/V+T is its reset output, which remains asserted for a minimum of 140ms after the supply voltage exceeds the reset threshold. This provides a reliable reset signal to the µP during power-up, power-down, and brownout conditions. The reset output is available in both active-low and active-high configurations, providing design flexibility to meet different system requirements.

Furthermore, this supervisory circuit consumes low quiescent current, making it suitable for battery-powered devices where power efficiency is critical. It also includes a manual reset input, allowing for a system reset to be triggered by external events or user intervention.

In summary, the MAX6320PUK46BY/V+T from Maxim Integrated is a robust and precise supervisory solution that offers critical protection for digital systems. Its compact size, low power consumption, and high accuracy make it an excellent choice for a wide range of applications, including portable devices, computers, controllers, and intelligent instruments.
