3 Description
The LMS33460 device is an undervoltage detector
with a 3‑V 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 V.
This part uses a precision on-chip voltage reference
and a comparator to measure the input voltage. Builtin
hysteresis helps to prevent erratic operation in the
presence of noise. The UVD is available in the ultraminiature
5-pin SC70 package.
