There are three clear automotive trends: the migration to semi-autonomous and autonomous vehicles, vehicles connected to the cloud with increasing data bandwidths, and vehicle electrification. These trends are driving changes to vehicle architectures.  By David Maples, General Manager, Texas Instruments

Texas Instruments has introduced the all-new TDA4VM and DRA829V SoCs for advanced ADAS and gateway systems, the first two SoCs in our new Jacinto 7 automotive processor platform. Additional SoCs will be introduced throughout the next few years.

The IWR1843 device from Texas Instruments is an integrated single-chip mmWave sensor based on FMCW radar technology capable of operating in the 76 to 81GHz band with up to 4-GHz continuous chirp. The device is built with the low-power 45nm RFCMOS process from Texas Instruments. This solution enables high levels of integration in an extremely small form factor.

The TDA4VM processor family is based on the evolutionary Jacinto 7 architecture, targeted at ADAS and Autonomous Vehicle (AV) applications and built on extensive market knowledge accumulated over a decade of TI’s leadership in the ADAS processor market.

C2000 32-bit microcontrollers from Texas Instruments are optimised for processing, sensing, and actuation to improve closed-loop performance in real-time control applications such as industrial motor drives; solar inverters and digital power; electrical vehicles and transportation; motor control; and sensing and signal processing. 

During my first visit to the US, my brother and I drove from New York City to Columbus, Ohio. Although the 650-KM (400-mile) journey was long, our car’s automatic transmission and cruise control made the trip more comfortable.  By Sandeep Tallada, Automotive Systems Engineer, Texas Instruments

This reference design from Texas Instruments provides power and data isolation for low and ultra-low power applications. Generating isolated and non-isolated power rails with a high efficiency and containing a power efficient isolated data interface for three forward- plus one reverse-direction channels. 

Arriving home late at night to a garage filled with bicycles, sports equipment and yard gear, you hope there is enough room to fit your car inside for the night. On a rainy and cold morning, the office parking lot is nearly full, with every available spot seemingly miles from the front door. 

The TLV320ADC5140 is a Burr-Brown high-performance, audio analogue-to-digital converter (ADC) that supports simultaneous sampling of up to four analogue channels or eight digital channels for the pulse density modulation (PDM) microphone input. The device supports line and microphone inputs, and allows for both single-ended and differential input configurations.

The INA333-Q1 from Texas Instruments is a low-power, precision instrumentation amplifier offering excellent accuracy. The versatile three-operational-amplifier design, small size, and low power make this device an excellent choice for a wide range of automotive applications that use resistive bridge sensors.

This reference design from Texas Instruments demonstrates how to create an industrial sensor-to-cloud end node capable of connecting to an IoT network gateway and cloud data provider. This design uses Texas Instruments’ nano-power operational amplifiers, comparators, and the SimpleLink ultra-low-power Sub-1 GHz wireless microcontroller (MCU) platform.

Proximity sensing with wide field-of-view (FoV) is getting more and more popular and important for people detection in many applications. This reference design from Texas Instruments uses optical time-of-flight (ToF) techniques to build small and cost-effective proximity sensor systems.

This high speed multi-channel data capture reference design from Texas Instruments enables optimum system performance. System designers needs to consider critical design parameters like clock jitter and skew for high speed multi-channel clock generation, which affects overall system SNR, SFDR, channel to channel skew and deterministic latency.

This reference design from Texas Instruments helps designers develop a cost optimised ultrasonic water-metering subsystem using an integrated, ultrasonic sensing solution (USS) module, which provides superior metrology performance with low-power consumption and maximum integration. 

The ISO7041 device from Texas Instruments is an ultra-low power, multichannel digital isolator that can be used to isolate CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by a double capacitive silicon dioxide (SiO2) insulation barrier.

The ISO7021 device from Texas Instruments is an ultra-low power, multichannel digital isolator that can be used to isolate CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by a double capacitive silicon dioxide (SiO2) insulation barrier. 

The BQ25155 from Texas Instruments is a highly integrated battery charge management IC that integrates the most common functions for wearable and portable devices, namely a charger, a regulated output voltage rail for system power, ADC for battery and system monitoring, a LDO, and push-button controller.

The ATL43xLI-Q1 from Texas Instruments is a three-terminal adjustable shunt regulator, with specified thermal stability over applicable automotive, commercial, and military temperature ranges. Its output voltage can be set to any value between Vref (approximately 2.5V) and 36V with two external resistors. The device has a typical output impedance of 0.3Ω. 

The TPS61391 from Texas Instruments is a 700kHz pulse-width modulating (PWM) step-up converter with an 85V switch FET with an input ranging from 2.5 to 5.5V. The switching peak current is up to 1,000mA. The TPS61391 includes accurate current mirror with two gain options selectable (1:5 or 4:5).
