Maxim Integrated MAX962ESA+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX962ESA+T is a highly reliable microprocessor (µP) supervisory circuit designed to maintain system integrity during power failures or unexpected behavior in digital systems. This compact device is an essential component for managing system resets and monitoring power supply voltages in microprocessor-based systems, ensuring that your application runs smoothly and reliably.

Encased in a small 8-pin SOIC package, the MAX962ESA+T is engineered to monitor power supplies in µP and digital systems. It provides a significant level of protection by asserting a reset signal whenever the VCC supply voltage falls below a preset threshold. The reset signal remains active for a minimum of 140ms after VCC has risen above the reset threshold, providing ample time for the system to stabilize before the processor is allowed to run.

One of the key features of the MAX962ESA+T is its ability to perform a low-battery monitoring function. This feature is particularly useful for portable devices, where it's critical to detect when the battery voltage drops to a level that could compromise the system's operation. The device also includes a manual reset input, which allows for an external trigger to initiate a system reset. This can be invaluable during system maintenance or in the event of a software freeze.

The MAX962ESA+T operates over a wide supply voltage range from 1V to 5.5V, making it versatile for various applications. It also boasts a low supply current of only 15µA, which is beneficial for power-sensitive designs. The device's quiescent current is particularly low, ensuring minimal power consumption during operation.

With its built-in features, the MAX962ESA+T from Maxim Integrated is an excellent choice for applications that require reliable voltage monitoring and system reset capabilities. It is particularly suited for use in computers, controllers, intelligent instruments, portable/battery-powered equipment, and other µP-based systems that demand high precision and reliability.

Whether you are designing a new system or upgrading an existing one, the Maxim Integrated MAX962ESA+T offers the performance and reliability needed to ensure your system operates without interruption.
