DATA SHEET www.onsemi.com Ultrasonic Parking Distance Measurement ASSP NCV75215 General Description 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. Under ideal conditions, with perfectly tuned and matched external circuitry, a minimum distance of 0.2 m is achievable. Actual detection range depends on a piezoelectric ultrasonic transducer and external analog parts. The device drives the ultrasonic transducer with a programmable frequency via a transformer.
