Abstract: Circuitry for driving a transducer for an object detection system, the circuitry comprising drive circuitry configured to generate a drive waveform for the transducer, current monitor circuitry for monitoring a current through the transducer, and system identification circuitry. The system identification circuitry is configured to determine a characteristic of the transducer based on a first signal indicative of a drive voltage for the transducer and a second signal indicative of the current through the transducer. The circuitry is operative to adjust the drive waveform based on the determined characteristic of the transducer.
