Product Overview: MAX697EPE+ from Maxim Integrated

The MAX697EPE+ is a high-performance microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in battery-powered systems. This supervisory circuit ensures that the µP always starts in a known state and maintains that state during power fluctuations and interruptions.

The device integrates a number of key features that make it a robust solution for complex electronic systems. The MAX697EPE+ includes a precision voltage monitor with a programmable reset threshold level, a watchdog timer to keep the µP system in check, a backup battery switchover function for reliable operation during power failures, and a power-fail comparator to provide early warning of impending power failure.

One of the standout features of the MAX697EPE+ is its ability to perform a power-on reset function, which ensures that the µP powers up in a predictable state every time. Additionally, the watchdog timer serves as an independent system monitor, preventing system failures due to runaway or stuck-in-one-place code by resetting the µP if it doesn't receive a periodic signal indicating normal operation.

With its wide operating voltage range, typically from 4.75V to 5.5V, and an operating temperature range from -40°C to +85°C, the MAX697EPE+ is versatile enough to accommodate a variety of applications, including computers, controllers, intelligent instruments, and critical µP power monitoring.

Available in a 16-pin DIP package, the MAX697EPE+ is easy to integrate into existing designs, and its industry-standard pinout makes it a drop-in replacement for other common supervisory circuits. This allows designers to upgrade their systems with the MAX697EPE+ without significant redesign or additional space requirements.

In summary, the MAX697EPE+ by Maxim Integrated is a comprehensive solution for µP system stability, offering a blend of monitoring functions that safeguard against power-related issues, ensuring reliable operation across a range of electronic applications.
