Computers Controllers Intelligent Instruments Critical µP and µC Power Monitoring Portable / Battery-Powered Equipment Automotive GENERAL DESCRIPTION
The G670/G671 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V- powered circuits. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold.
