Maxim Integrated MAX699CWE+T - Microprocessor Supervisory Circuit

The Maxim Integrated MAX699CWE+T supervisory circuit is a highly reliable component designed to monitor microprocessor (µP) systems, providing essential protection and monitoring functionality. This precision circuit is engineered to ensure that your microprocessor system operates within safe parameters, enhancing the overall stability and dependability of your electronic applications.

The MAX699CWE+T supervisory circuit offers a wide range of features that make it an indispensable part of any microprocessor-based system. It provides a reset output during power-up, power-down, and brown-out conditions. The reset signal ensures that the µP and its peripherals are reset to a known, stable state, preventing software execution errors due to incomplete initialization.

This device includes a backup battery switchover function that maintains uninterrupted power supply to the memory when the main power fails. The battery freshness seal ensures that the backup battery remains unused until the main power is applied for the first time, preserving its shelf life. The MAX699CWE+T also features a write protection mechanism for nonvolatile memory, safeguarding critical data during adverse power conditions.

Key specifications of the MAX699CWE+T include a reset threshold voltage tailored for 5V-powered systems, a reset timeout period that provides a minimum of 200ms reset pulse width, and an operating temperature range of 0°C to +70°C. The device is available in a 16-SOIC package, making it suitable for surface-mount technology (SMT) and ideal for compact designs.

The MAX699CWE+T is a versatile component that can be used in a variety of applications, such as computers, controllers, intelligent instruments, and portable/battery-powered equipment. Its robust design ensures that your system is protected from unpredictable power fluctuations, contributing to the longevity and reliability of your product.

With Maxim Integrated's reputation for quality and innovation, the MAX699CWE+T supervisory circuit is a smart choice for designers looking to add a layer of protection to their microprocessor systems without compromising on performance or space.
