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 (G690L) Push-Pull RESET Output (G690H) Open-Drain RESET Output (G691L) 140ms min Power-On Reset Pulse Width 10µA Supply Current Guaranteed Reset Valid to VCC = +1V Power Supply Transient Immunity No External Components 3-Pin SOT89, SOT23 and SC70 Packages Applications Computers Controllers Intelligent Instruments Critical µP and µC Power Monitoring Portable / Battery-Powered Equipment Automotive General Description The G690/G691 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- pow- ered circuits. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The G691L has an open-drain output stage, while the G690 have push-pull outputs. The G691L’s open-drain RESET output requires a pull-up resistor that can be connected to a voltage higher than VCC. The G690L have an active-low RESET output, while the G690H 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 1V. Low supply current makes the G690/G691 ideal for use in portable equipment. The G690/G691 are avail- able in 3-pin SOT89 or SOT23 or SC70 packages.
