These microprocessor (µP) supervisory circuits reduce the complexity and number of components required for power-supply monitoring and battery control functions in µP systems. 802R significantly improve system reliability and accuracy compared to separate ICs or discrete components.
802R are designed for use in systems powered by 3.0V or 3.3V supplies. See the selector guide in the back of this data sheet for similar devices designed for 5V systems. The suffixes denote different reset threshold voltages: 3.075V (T), 2.925V (S), and 2.625V (R) (see Reset Threshold section in the Detailed Description). All these parts are available in 8-pin DIP and SO packages.
