MAX690A Overview
The MAX690A/MAX692A/MAX802L/MAX802M/MAX805L reduce the plexity and number of ponents required for power-supply monitoring and batterycontrol functions in microprocessor (μP) systems. They significantly improve system reliability and accuracy pared to separate ICs or discrete ponents. These parts provide four functions:.
