Key Document


This reference design provides hardware architecture for a Park Assist System (PAS) using three highly integrated, system-on-chip (SoC) ultrasonic transducer drivers. These ultrasonic transducer drivers have an integrated signal conditioner with an advanced digital signal processor (DSP) core. Using these integrated features, object detection from 25cm to 2.5m is achieved. The distance data is sent over a one-wire interface (OWI) to a local electronics control unit (ECU) where the data can be aggregated and processed. The sensor initialization, object detection algorithm, and software described in this design guide provide a basic framework to help engineers working on PAS for automotive or collision avoidance.

  • Combines three PGA460-Q1 devices to detect objects from 25cm to 2.5m
  • Provides system diagnostic information
  • Circuitry for level USART and TCI interface option included
  • 22mm diameter solution size
