♦ 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

♦ 40µA V Supply Current

♦ 1µA Battery Supply Current

♦ Voltage Monitor for Power-Fail or

Low-Battery Warning

–————–

♦ Guaranteed RESET Assertion to V = 1V

♦ 8-Pin DIP and SO Packages
