MAX690RESA+

The MAX690RESA+ 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.
