Maxim Integrated's MAX825TEUK-T Microprocessor Supervisory Circuit

The MAX825TEUK-T from Maxim Integrated is a highly efficient microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low-cost solution by ensuring that all the system's voltages are within acceptable limits. This supervisory circuit is crucial for systems that require a high level of operational stability and accuracy.

The device is available in a small 5-pin SOT23 package, making it ideal for space-constrained applications. It is specifically tailored to offer precision monitoring of 3V, 3.3V, and 5V power-supply voltages. This component is perfect for portable devices, computers, controllers, and intelligent instruments where size and power consumption are critical factors.

One of the key features of the MAX825TEUK-T is its ability to assert a reset signal whenever the VCC supply voltage falls below a preset threshold, ensuring that the µP boots up in a known state. The reset signal remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, providing ample time for the system to stabilize.

In addition to its reset function, the MAX825TEUK-T offers a manual reset feature. This allows for a system reset to be initiated by an external push-button or logic signal, giving users direct control over the reset process. This is particularly useful for debugging and testing purposes, as well as for user-initiated system reboots.

The device boasts a low supply current of only 3µA (typical), which is ideal for battery-operated applications. Its wide operating temperature range of -40°C to +85°C ensures that it can perform reliably in a variety of environments, from industrial to commercial settings.

Overall, the MAX825TEUK-T is a robust solution for system monitoring, offering features that enhance the reliability and performance of electronic systems. Its integration into a design ensures that the digital system operates effectively, maintaining the integrity of the processes and data within.
