The LMS33460MG/NOPB is an Under-voltage Detector with open-drain output. The under-voltage detector has a 3V 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 sizes are required. This IC generates an active output whenever the input voltage drops below 3V. 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.
