Microprocessor Supervisory Circuit with Low Line
Output
General DescriptionThe LM3700/LM3701 seriesof microprocessor supervisory
circuits providethe maximum flexibilityfor monitoring power
supplies and battery controlled functionsin systems without
backup batteries. The LM3700/LM3701 series are availablea 9-bump micro SMD package.
Built-in features includethe following:
Reset: Resetis asserted during power-up, power-down, and
brownout conditions. RESETis guaranteed downto VCCof
1.0V.
Low Line Output: This early power failure warning indicator
goes low whenthe supply voltage dropstoa value whichis higher than the reset threshold voltage.
Features Standard Reset Threshold voltage: 3.08V Custom Reset Threshold voltages: For other voltages
between 2.2V and 5.0Vin 10mV increments, contact
National Semiconductor Corp. No external components required RESET (LM3700)or RESET (LM3701) outputs Precision supply voltage monitor Factory programmable Reset Timeout Delay Availablein micro SMD packagefor minimum footprint ±0.5% Reset threshold accuracyat room temperature ±2% Reset threshold accuracy over temperature
extremes Reset assertion downto1V VCC (RESET option only)28µA VCC supply current
