Product Summary
The MAX802LESA is a Microprocessor Supervisory Circuit. The MAX802LESA reduces the complexity and number of components required for power-supply monitoring and battery-control functions in microprocessor (μP) systems. They significantly improve system reliability and accuracy compared to separate ICs or discrete components. The applications of the MAX802LESA include Battery-Powered Computers and Controllers, Intelligent Instruments, Automotive Systems, Critical μP Power Monitoring.
