Microprocessor Supervisory Circuits with Power Fail Input, Low Line Output and Manual Reset
LM3704/LM3705
Microprocessor Supervisory Circuits with Power Fail
Input, Low Line Output and Manual Reset
General DescriptionThe LM3704/LM3705 seriesof microprocessor supervisory
circuits providethe maximum flexibilityfor monitoring power
supplies and battery controlled functionsin systems without
backup batteries. The LM3704/LM3705 series are available MSOP-10 and 9-bump micro SMD packages.
Built-in features includethe following:
Reset: Resetis asserted during power-up, power-down, and
brownout conditions. RESETis guaranteed downto VCCof
1.0V.
Manual Reset Input:An input that asserts reset when pulled
low.
Power-Fail Input:A 1.225V threshold detectorfor powerfail
warning,orto monitora power supply other than VCC.
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
