MAXIM INTEGRATED PRODUCTS  MAX704RESA+  芯片, 微处理器监控器, 5.5V, NSOIC-8

The is a microprocessor µP supervisory circuit in 8 pin NSOIC package. This supervisory circuit reduces the complexity and number of components required for power supply monitoring and battery control functions in µP systems. It significantly improves system reliability and accuracy compared to separate IC"s or discrete components. This device is designed for use in systems powered by 3V or 3.3V supplies. Typical applications include battery powered computers and controllers, embedded controllers, intelligent instruments and critical µP power monitoring.
