LP3808N-11B3F

Preliminary Datasheet LP3808 High-precision Low Voltage Detector General Description Features LP3808 is a series of high precision voltage detector  High-precision detection Voltage 2% with ultra low current consumption(500nA typ. at  Detection Voltage 0.9V~6.0V (in 0.1V steps) Vdd=3.0V). It can work at very low voltage, which  Precise hysteresis 4% typ. makes it perfect for system reset.  Operating Voltage range 0.7V~10V LP3808 is composed of high precision voltage  Ultra-low current consumption 500nA typ. (at VDD 3.0V) reference, comparator, output driver and resistor array. Internally preset detect voltage has a low temperature  Two Output forms N-channel open-drain drift and requires no external trimming. Two type of output, N-channel open-drain are Applications available.LP3808  Power monitor for portable equipment such as  PDA, DSC, Mobile phone,Notebook,MP3  CPU and Logic Circuit Reset  Battery Checker  Battery Back-up Circuit  Power Failure Detector is available in SOT-89-3 ， SOT-23-3，SOT23-5 packages which is Pb -free.
