The MAX819LEUA+ from Analog Devices is a microprocessor supervisory circuit designed to simplify power-supply monitoring and battery control in µP systems. It operates in +5V powered systems and features a precision supply-voltage monitor set at 4.65V for the L versions. The device boasts a low quiescent supply current of 11µA, making it suitable for portable applications.
Key supervisory functions include an active-low reset with a 140ms minimum timeout, battery backup power switching, and a battery freshness seal. The MAX819 variant specifically includes an uncommitted voltage monitor for power-fail or low-battery warnings and a manual reset input. It is designed to ignore fast transients on VCC.
This component is available in a space-saving 8-uMAX package and is designed for surface mount applications. Its compact size and low power consumption make it ideal for embedded controllers, intelligent instruments, and critical µP monitoring in battery-powered computers and portable equipment.
