NCV75215 - Ultrasonic Parking Distance Measurement ASSP

General Description

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.

Key Features

  • Measurement Distance Range from 0.25 m to 4.5 m (depends on External Parts).
  • Acoustic Noise Monitoring.
  • Transducer Resonant Period Measurement.
  • Diagnosis of Transducer Performance.
  • Junction Temperature Monitoring and Thermal Shutdown.
  • Transducer Center Frequency Range from 35 to 90 kHz.
  • Direct and Indirect Measurement Modes.
  • EEPROM Memory for Configuration Setting and User Data.
  • Rx Gain Adjustable in 0.5 dB Steps i.

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 programma
