MAX690TCSA+ by Analog Devices

3.0V/3.3V Microprocessor Supervisory Circuits


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 reliability and accuracy compared to separate ICs or discrete components. 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: Part Active-Low Reset Active-High Reset Watchdog Input Manual Reset Input Backup-Battery Switch Power-Fail Threshold Accuracy Power-Fail Comparator Reset Window MAX690 √   √   √ ±4% √ ±75mV MAX704 √     √ √ ±4% √ ±75mV MAX802 √   √   √ ±2% √ ±2% MAX804   √ √   √ ±2% √ ±2% MAX805   √ √   √ ±4% √ ±75mV MAX806 √     √ √ ±2% √ ±2%
