SNVS158E –MARCH 2001–REVISED DECEMBER 2016

LMS33460 3-V Undervoltage Detector

1 Features

3 Description

The LMS33460 device is an undervoltage detector

•

Ultra-Low Power

3-V Detection

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.

Input Voltage From 0.8 V to 7 V

Open-Drain Output

Ultra-Small 5-Pin SC70 Package

Extended Temperature Range (–40°C to 85°C)

Ultra-Low Quiescent Current (1 µA Typical)

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 5-pin SC70 package.
