♦ RESET and RESET Outputs  
♦ Manual Reset Input  
–————–  
These microprocessor (µP) supervisory circuits reduce  
the complexity and number of components required for  
power-supply monitoring and battery-control functions  
in µP systems. They significantly improve system relia-  
b ility a nd a c c ura c y c omp a re d to s e p a ra te ICs or  
discrete components.  
♦ Precision Supply-Voltage Monitor  
♦ 200ms Reset Time Delay  
♦ Watchdog Timer (1.6sec timeout)  
♦ Battery-Backup Power Switching—  
These devices 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.  
Functions offered in this series are as follows:  
Battery Can Exceed V in Normal Operation  
CC  
♦ 40µA V Supply Current  
CC  
♦ 1µA Battery Supply Current  
♦ Voltage Monitor for Power-Fail or  
Low-Battery Warning  
–————–  
♦ Guaranteed RESET Assertion to V = 1V  
CC  
♦ 8-Pin DIP and SO Packages
