LP3810
概述
LP3809 is a series of high precision voltage detector with ultra low current consumption. It can work at very low voltage, which makes it perfect for system reset.LP3809 is composed of high precision voltage reference, comparator, delay circuit, output driver and resistor array. Internally preset detect voltage has a low temperature drift and requires no external trimming.LP3809 is available in SOT-23 packages which are Pb free.
