MAX703 Description
The MAX703/MAX704 microprocessor (μP) supervisory circuits reduce the plexity and number of ponents required for power-supply monitoring and battery control functions in μP systems. These devices significantly improve system reliability and accuracy pared to that obtained with separate ICs or discrete ponents. The MAX703/MAX704 are available in 8-pin DIP and SO packages and provide four functions:.
