n Available in micro SMD package for minimum footprint  
General Description  
The LM3706/LM3707 series of microprocessor supervisory  
circuits provide the maximum flexibility for monitoring power  
supplies and battery controlled functions in systems without  
backup batteries. The LM3706/LM3707 series are available  
in a 9-bump micro SMD package.

0.5% Reset threshold accuracy at room temperature  
2% Reset threshold accuracy over temperature  
Built-in features include the following:  
Reset: Reset is asserted during power-up, power-down, and  
brownout conditions. RESET is guaranteed down to VCC of  
1.0V.  
extremes  
n Reset assertion down to 1V VCC (RESET option only)  
n 28 µA VCC supply current  
Low Line Output: This early power failure warning indicator  
goes low when the supply voltage drops to a value which is  
2% higher than the reset threshold voltage.  
Applications  
n Embedded Controllers and Processors  
n Intelligent Instruments  
Watchdog Timer: The WDI (Watchdog Input) monitors one of  
the µP’s output lines for activity. If no output transition occurs  
during the watchdog timeout period, reset is activated.  
n Automotive Systems  
n Critical µP Power Monitoring  
Features  
n Standard Reset Threshold voltage: 3.08V  
n Custom Reset Threshold voltages: For other voltages  
between 2.2V and 5.0V in 10mV increments, contact
