LM3704XCMM-308/NOPB Datasheet PDF - TI

●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 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

●• Custom Reset Threshold Voltages: For Othe

●Voltages Between 2.2V and 5.0V in 10mV
