FEATURES  
DESCRIPTION  
The LM3700/LM3701 series of microprocessor  
supervisory circuits provide the maximum flexibility for  
monitoring power supplies and battery controlled  
functions in systems without backup batteries. The  
LM3700/LM3701 series are available in a 9-bump  
micro SMD package.

Standard Reset Threshold Voltage: 3.08V  
Custom Reset Threshold Voltages: For Other  
Voltages between 2.2V and 5.0V in 10mV  
Increments, Contact Texas Instruments.  
No External Components Required  
RESET (LM3700) or RESET (LM3701) Outputs  
Precision Supply Voltage Monitor  
Built-in features include the following:  
Reset: Reset is asserted during power-up, power-  
down, and brownout conditions. RESET is specified  
down to VCC of 1.0V.  
Factory Programmable Reset Timeout Delay  
Available in micro SMD Package for Minimum  
Footprint  
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.  
±0.5% Reset Threshold Accuracy at Room  
Temperature  
±2% Reset Threshold Accuracy Over  
Temperature Extremes  
Reset Assertion Down to 1V VCC (RESET  
Option Only)  
28 µA VCC Supply Current
