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.
