LMS33460
3V Under Voltage Detector
General Description
The LMS33460 is an under voltage detector with a 3.0V
threshold and extremely low power consumption. The
LMS33460 is specifically designed to accurately monitor
power supplies. It is especially suited to battery powered
systems where low quiescent current and small size are
required. This IC generates an active output whenever the
input voltage drops below 3.0 Volts.
This part uses a precision on-chip voltage reference and a
comparator to measure the input voltage. Built in hysteresis
helps to prevent erratic operation in the presence of noise.
The UVD is available in the ultra-miniature SC70-5 package.
