Global Mixed-mode Technology Inc. G670/G671 Microprocessor Reset IC Features Precision Monitoring of +3V, +3.3V, and +5V Power-Supply Voltages 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. Reset thresholds suitable for operation with a variety of supply voltages are available. The G671L has an open-drain output stage, while the G670 have push-pull outputs. The G671L’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The G670L have an active-low RESET output, while the G670H has an active-high RESET output. The reset comparator is designed to ignore fast transients on VCC, and the outputs are guaranteed to be in the correct logic state for VCC down to 1V. Fully Specified Over Temperature Available in Three Output Configurations Push-Pull RESET Output (G670L) Push-Pull RESET Output (G670H) Open-Drain RESET Output (G671L) 2ms max Power-On Reset Pulse Width 14µA Supply Current Guaranteed Reset Valid to VCC = +1V Power Supply Transient Immunity No External Components 3-Pin SOT-23,TO-92 and SOT-89 Packages 2% Threshold Accuracy Applications Computers Controllers Intelligent Instruments Critical µP and µC Power Monitoring Portable / Battery-Powered Equipment Automotive Low supply current makes the G670/G671 ideal for use in portable equipment. The G670/G671 are available in 3-pin SOT-23, TO-92 and SOT-89 packages.
