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.
