Microprocessor Reset IC Features Precision Monitoring of +3V, +3.3V, and +5V Power-Supply Voltages Fully Specified Over Temperature Available in Three Output Configurations Push-Pull RESET Output (G684L) Push-Pull RESET Output (G684H) Open-Drain RESET Output (G685L) 14µA Supply Current Guaranteed Reset Valid to VCC = 0.8V Power Supply Transient Immunity 5 pin SOT23-5 Packages 2% Threshold Accuracy Applications Computers Controllers Intelligent Instruments Critical µP and µC Power Monitoring Portable / Battery-Powered Equipment Automotive General Description The G684/G685 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost 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, with hysteresis after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The G685 has an open-drain output stage, while the G684 have push-pull outputs. The G685L’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The G684L have an active-low RESET output, while the G684H has an active-high RESET output. The reset com- parator is designed to ignore fast transients on VCC, and the outputs are guaranteed to be in the correct logic state for VCC down to 0.8V. Low supply current makes the G684/G685 ideal for use in portable equipment. The G684/G685 are avail- able in 5-pin SOT23-5 packages. Ordering Information ORDER NUMBER TEMP.
