LM3700/LM3701 Microprocessor Supervisory Circuit with Low Line Output

Check for Samples: LM3700, LM3701

FEATURES

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.

•

Standard Reset Threshold Voltage: 3.08V

•

Custom Reset Threshold Voltages: For Other

Voltages between 2.2V and 5.0V in 10mV

Increments, Contact Texas Instruments.

•

No External Components Required

RESET (LM3700) or RESET (LM3701) Outputs

Precision Supply Voltage Monitor

Built-in features include the following:

Reset: Reset is asserted during power-up, power-

down, and brownout conditions. RESET is specified

down to V_CCof 1.0V.

Factory Programmable Reset Timeout Delay

Available in micro SMD Package for Minimum

Footprint

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.

•

±0.5% Reset Threshold Accuracy at Room

Temperature

±2% Reset Threshold Accuracy Over

Temperature Extremes

Reset Assertion Down to 1V V_CC(RESET

Option Only)

28 µA V_CCSupply Current
