The MAX691EWE is a supervisory circuit from Analog Devices Inc. that integrates essential power supply monitoring and battery control functions for microprocessor systems. This device reduces component count and enhances system reliability.
Key features include a precision voltage monitor set at 4.65V, providing power-fail warning or low battery detection. It offers both active high and active low reset outputs, ensuring proper system initialization during power-up, power-down, and brownout conditions. The MAX691EWE also includes battery backup power switching for CMOS RAM or other low-power logic, and a watchdog timer to monitor microprocessor activity.
This supervisory circuit is supplied in a 16-SOIC package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA). The integration of multiple functions into a single IC saves board space and simplifies designs for critical microprocessor power monitoring applications.
Applications include computers, controllers, intelligent instruments, and automotive systems where robust power monitoring is crucial.
