LP3808 - High-precision Low Voltage Detector

General Description

LP3808 is a series of high precision voltage detector with ultra low current consumption(500nA typ.

at Vdd=3.0V).

It can work at very low voltage, which makes it perfect for system reset.

Key Features

  • High-precision detection Voltage 2%.
  • Detection Voltage 0.9V~6.0V (in 0.1V steps).
  • Precise hysteresis 4% typ.
  • Operating Voltage range 0.7V~10V.
  • Ultra-low current consumption 500nA typ. (at VDD 3.0V).
  • Two Output forms CMOS and N-channel open-drain Two type of output, CMOS and N-channel open-drain are available. LP3808 is available in SOT-89-3,SOT-23-3, SOT23-5 packages which is Pb -free. Order Information LP3808 -.

Preliminary Datasheet LP3808 High-precision Low Voltage Detector General Description LP3808 is a series of high precision voltage detector with ultra low current consumption(500nA typ. at Vdd=3.0V). It can work at very low voltage, which makes it perfect for system reset. LP3808 is composed of high precision voltage reference, comparator, output driver and resistor array. Internally preset detect voltage has a low temperature drift and requires no external trimming.
