FEATURES - 2 Standard Reset Threshold Voltage: 3.08V - Custom Reset Threshold Voltages: For Other Voltages between 2.2V and 5.0V in 10m V Increments, Contact Texas Instruments. - No External ponents 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 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, powerdown, and brownout conditions. RESET is specified 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.
