GENERAL DESCRIPTION
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. n n n n n n n 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 n Reset assertion down to 1V VCC (RESET option only) n 28 µA VCC supply current APPLICATIONS
