供应LP3803 微源低压探测器 SOT23封装

微源半导体 LP3803 SOT23 高精度低压探测器

General description

LP3803 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.

LP3803 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.

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