The MAX691EWE+ is a supervisory circuit from Analog Devices Inc. that integrates multiple functions to reduce system complexity and component count in microprocessor-based systems. It provides a reset output during power-up, power-down, and brownout conditions, along with battery backup switching for CMOS RAM or other low-power logic.
Key electrical features include a precision voltage monitor set at 4.65V, an active high/active low reset output, and a minimum reset timeout of 35ms. The device also includes a watchdog timer with adjustable timeout periods and a 1.3V threshold detector for power-fail warning or low battery detection.
This supervisory circuit is supplied in a 16-SOIC package, measuring 0.295" (7.50mm) in width, and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C (TA). The MAX691 family significantly improves system reliability and accuracy compared to discrete components.
Applications for the MAX691EWE+ include computers, controllers, intelligent instruments, automotive systems, and critical microprocessor power monitoring. Its integrated features save board space while fully protecting microprocessor-based systems.
