NS LM3705XCBP-308

简单复位/加电复位3.08V1

Overview

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 Increments, Contact Texas Instruments. • No External Components Required • Manual-Reset Input • Precision Supply Voltage Monitor • Factory Programmable Reset Timeout Delay • Separate Power Fail Comparator • Available in DSBGA Package for Minimum Footprint
