LP3809-263B3F

Preliminary Datasheet LP3809 Reset, Low Voltage Detector Built-in Delay 240mS General Description Features LP3809 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~5.5V (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 2.5V~5.5V LP3809 is composed of high precision voltage  Ultra-low current consumption 500nA typ. (at VDD 3.0V) reference, comparator, delay circuit, output driver and resistor array. Internally preset detect voltage has a low temperature drift and requires no external Applications trimming.  Power monitor for portable equipment LP3809 is available in SOT-23-3 packages which are  PDA, DSC, Mobile phone,Notebook,MP3 Pb free.  CPU and Logic Circuit Reset  Battery Checker  Battery Back-up Circuit  Power Failure Detector Order Information LP3809 - □ □ □ □ □ F:Pb-Free Package Type B3: SOT23-3 Detector Voltage Marking Information Device LP3809-263B3F 09: 0.9V 263: 2.63V 270: 2.70V 293: 2.93V 308: 3.08V LP3809-293B3F Marking Package Shipping LPS SOT23-3 3K/REEL SOT23-3 3K/REEL AFYW LPS ADYW Marking indication: Y:Production year W:Production week 440: 4.40V LP3809-06 Mar.-2017 Email: marketing@lowpowersemi.com www.lowpowersemi.com Page 1 of 6 Preliminary Datasheet LP3809 Pin Assignment Package Type Pin Configurations 3 SOT23-3 1 2 Pin Description Pin Number Pin Name Function 1 VSS GND pin. 2 Vout Voltage detection output pin. 3 VDD Voltage input pin.
