APPLICATION CIRCUIT INFORMATION
The LMS33460 is a micro power under voltage sensing circuit with an open drain output configuration, which
requires a pull resistor.
The LMS33460 features a voltage reference, a comparator with precise thresholds and built in hysteresis to
prevent erratic reset operation.
