This processor supply reference design is an automotive power solution for use in highperformance, single-core-voltage application processors in advanced driver assistance systems (ADASs). This design can support core supply currents up to 10 A at 0.9 V. The design can also operate with a wide input voltage range, withstand reverse battery conditions, and support start-stop and cold-crank down to a 3.5-V input with an undisturbed output. All switching frequencies in this solution are above 2 MHz. The design has an inherently lower electromagnetic interference (EMI) and higher efficiency due to the multi-phase configuration and integration of supplies. This reference design also provides results for conducted emissions tests for CISPR 25 Class 5.
Возможности:

5A integrated 2.2MHz synchronous wide input voltage buck converter Smart diode reverse battery protection for minimum voltage drop (typical 20mV) Operating range 3.5 - 36V, supports start-stop and cold-crank Interleaved four-phase core-voltage supply minimizing ripple, EMI and inductor size Optimized for CISPR 25 Class 5 conducted emissions Small switched cap boost for 5V CAN supply reduces solution size and BOM cost

The design can also operate with a wide input voltage range, withstand reverse battery conditions, and support start-stop and cold-crank down to a 3.5-V input with an undisturbed output. The sub-AM band switching frequency of the power front end improves efficiency and reduces board temperatures when compared to a power front end with faster switching frequency. The multiphase configuration and integration of supplies enables lower electromagnetic interference (EMI) and higher efficiency. This reference design also provides results for conducted emissions tests for CISPR 25 Class 5.

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.
