onsemi NCV75215 Ultrasonic Sensor

Parking distance measurement ASSP

The onsemi 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.

The actual detection range depends on a piezoelectric ultrasonic transducer and external analog parts.

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 in the Range from 50 to 110 dB
  • Time-dependent Threshold Values for the Sensitivity Control
  • Dynamic (Time-dependent) Gain Control
  • Tx Current Range Adjustable from 50 mA to 350 mA
  • 12V Supply (6V to 18V operating voltage)

Applications

  • Automotive Park Assist
  • Automotive Emergency Brake

 

  • Automotive Blind Spot Detection
  • Ultrasonic Distance Measurements
