SNVS158E – MARCH 2001 – REVISED DECEMBER 2016 LMS33460 3-V Undervoltage Detector
1 Features 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. 1 Ultra-Low Power
3-V Detection
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 ВµA Typical) 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. 2 Applications Low Battery Voltage Detectors …
