Ультразвуковой парктроник

Описание:
The TIDA-00151 reference design contains a PGA450-Q1 which is a system on Chip (SOC) sensor interface IC for automotive Ultrasonic sensors. It provides all signal conditioning and processing for the transducer echo signals and for calculating the distance between the transducer and objects. MCU and program memory allow for full configurability for the specific end application. Application examples are ultrasonic park assist, self parking, blind spot detection and valet parking. The design files for a small form factor board are included in this design, but thePGA450Q1EVM board was used to collect the test data.

Возможности:

Flexibility in transducer selection (40 kHz – 70 kHz) SoC that is highly programmable with integrated 8051 core Integrated LIN2.1 master transceiver Can be directly connected to car battery, no wide input range LDO required Load dump protection AEC Q-100

Описание:
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.
Возможности:

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
