Maxim Integrated MAX825SEXK+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX825SEXK+T is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides maximum flexibility and control to enhance system stability and safety. This compact supervisory circuit is ideal for use in a vast array of applications, including portable devices, computers, controllers, and intelligent instruments.

The MAX825SEXK+T is part of Maxim Integrated's extensive range of supervisory circuits that are engineered to maintain system integrity through monitoring critical functions. It offers key features such as a reset output during power-up, power-down, and brownout conditions. This ensures that the µP and its peripherals are reset cleanly when power is unstable or when the device is first powered on.

One of the standout features of this device is its low power consumption, drawing a quiescent current of only 3.5µA at +3.3V, which is particularly beneficial for battery-powered applications where power efficiency is crucial. The MAX825SEXK+T operates over a wide voltage range from +1.2V to +5.5V, making it versatile for different system voltages.

The supervisory circuit also includes a manual reset input, allowing for a system reset to be triggered with an external switch or logic signal. This is a critical feature for systems that require user-initiated resets or for implementing a remote reset capability. The reset output is available in both push-pull and open-drain configurations, providing design flexibility to interface with various logic levels and drive capabilities.

Furthermore, the MAX825SEXK+T comes in a small, 5-pin SC70 package, which is ideal for space-constrained applications. Its temperature range of -40°C to +85°C ensures reliable operation in harsh environments, making it suitable for industrial and automotive applications as well.

Maxim Integrated's commitment to quality and reliability is evident in the MAX825SEXK+T supervisory circuit, making it a trusted choice for designers looking to enhance their system's performance and stability.
