General Description

The LM3710/LM3711 seriesof microprocessor supervisory
circuits providethe maximum flexibilityfor monitoring power
supplies and battery controlled functionsin systems without
backup batteries. The LM3710/LM3711 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.
Watchdog Timer: The WDI (Watchdog Input) monitors oneof
the µP’s output linesfor activity.Ifno output transition occurs
during the watchdog timeout period, resetis activated.
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 Manual-Reset input RESET (LM3710)or RESET (LM3711) outputs Precision supply voltage monitor Factory programmable Reset and Watchdog Timeout
Delays Separate Power Fail comparator Availablein micro SMD packagefor minimum footprint ±0.5% Reset threshold accuracyat room temperature ±2% Reset threshold accuracy over temperature
