G690/G691  
Microprocessor Reset IC  
Features  
General Description  
„Precision Monitoring of +3V, +3.3V, and +5V  
Power-Supply Voltages  
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.  
„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  
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.  
„Guaranteed Reset Valid to VCC = +1V  
„Power Supply Transient Immunity  
„No External Components  
„3-Pin SOT89, SOT23 and SC70 Packages  
The G691L has an open-drain output stage, while the  
G690 have push-pull outputs. The G691L’s open-drain  
Applications  
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-

„Portable / Battery-Powered Equipment  
„Automotive  
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.
