Preliminary Datasheet

LP3818

Reset, Low Voltage Detector Built-in Delay 200ms

General Description

LP3818 is a series of high precision voltage detector

with ultra low current consumption (5uA typ. at

Vdd=3.0V). It can work at very low voltage, which

makes it perfect for system reset.

LP3818 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.

Two type of output, CMOS and N-channel open-drain

are available.LP3818 is available in SOT-23-3

packages which is Pb free.
