DESCRIPON

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 VSSOP-10 and 9-bump DSBGA packages.

Built-in features include the following: Reset: Reset is asserted during power-up, power

down, and brownout conditions. RESET is ensured 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 the reset threshold voltage.

2• Standard Reset Threshold Voltage: 3.08V
