LVD is a low power voltage detection chip, there are two forms of NMOS open drain output and CMOS output. Mainly used in mobile phone, MP3 / MP4 player, cordless telephone, radio communication equipment, a three meter (ammeter, water meter and gas meter), digital camera, interface converter, car alarm, electronic locks and other occasions. Typical application circuit diagram is as follows:
