General 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.

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.

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.

Features

  • Standard Reset Threshold voltage: 3.08V
  • Custom Reset Threshold voltages: For other voltages between 2.2V and 5.0V in 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
  • Available in micro SMD package for minimum footprint
  • ±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

Applications

  • Embedded Controllers and Processors
  • Intelligent Instruments
  • Automotive Systems
  • Critical µP Power Monitoring
