NCV75215 Overview
The NCV75215 ASSP is intended to operate with a piezoelectric ultrasonic transducer to provide time-of-flight measurement of an obstacle distance during vehicle parking. The high-sensitivity, low-noise operation allows detection from 0.25 m up to 4.5 m for a standard 75 mm pole. Actual minimum distance is determined by the length of reverberations.
