Description

This is Microprocessor Supervisory Circuits with Power Fail Input/ Low Line Output and Manual Reset. LM3704, LM3705 Microprocessor Supervisory Circuits with Power Fail Input, Low Line Output and Manual Reset July 2002 LM3704, LM3705 Microprocessor Supervisory Circuits with Power Fail Input, Low Line Output and Manual Reset General Description The LM3704, LM3705 series of microprocessor supervisory circuits provide the maximum flexibility for monitoring power supplies and battery controlled functions in systems without backup batteries. The LM3704, LM3705 series are available in MSOP-10 and 9-bump micro SMD packages. 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. Manual Reset Input: An input that asserts reset when pulled low. Power-Fail Input: A 1.225V threshold detector for power fail warning, or to monitor a power supply other than VCC. Low Line Output: This early power failure warning indicator goes low when the supply voltage drops to a value which is 2% higher than .
