LMS33460 3V Under Voltage Detector March 2001 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.
