【文字介紹】

The PGA450-Q1 is a fully integrated interface device for ultrasonic transducers used in automotive park distance or object detection applications. It incorporates these system blocks: voltage regulators, a 12-bit SAR ADC, an 8-bit microcontroller, a digital band-pass filter, a DAC, dual NMOS low-side drivers, a low-noise amplifier, an oscillator, and a LIN 2.1 physical interface and protocol for interfacing.

The PGA450-Q1 possesses an 8-bit microcontroller and OTP memory for program storage for processing the echo signal and calculating the distance between the transducer and the object. This data is transmitted through the LIN 2.1 communication protocol. The LIN 2.1 physical layer is slave-only and does not implement the LIN wake-up feature. All other LIN 2.1 features can be implemented in software.
