Riding Out Automotive Transients : Architecting Front End Power Conversion Stage for Automotive Off-Battery Loads
With rapidly expanding electronic content in latest generation of cars, there is an ever increasing need for power conversion from the car battery rail. The 12-V battery rail is subject to a variety of transients. This presents a unique challenge in terms of the power architecture for off-battery systems. This presentation introduces the different types of transients that occur in automotive battery rails, the causes of those transients, and the standards and specifications defining the test conditions for those transients.

The DS90UB953/954 System Design & Operation video series offers training for FPD-Link III devices for ADAS. FPD-Link III devices such as the DS90UB953-Q1/ DS90UB954-Q1 support sensor use over serial link for Advanced Driver Assist Systems (ADAS) in the automotive industry. In this training series, we will guide you through step-by-step procedures to initialize and bring-up the “Sensor-Serializer-Deserializer-ISP” link to an optimal performance level.
The FPD-Link Learning Center is a comprehensive online classroom for system designers integrating FPD-Link serializer/deserializer technology into their ADAS or infotainment applications. The on-demand curriculum offers subject matter, from basics to advanced, to widen the technical knowledge of experienced engineers as well as assist those who are just starting to design with FPD-Link serializers and deserializers.
As the number of complex electronic features in vehicles increase, body control modules (BCMs) are rapidly evolving to keep up. All semiconductor devices in a BCM have one thing in common – they all need power. This training series will go over the various power topologies needed in a BCM in a vehicle.
TI's Jacinto TDA2/TDA3 System-on-Chip (SoC) family offers scalable and open solutions based on a heterogeneous hardware and common software architecture for Advanced Driver Assistance System (ADAS) applications including camera-based front (mono/stereo), rear, surround view and night vision systems in addition to multi-range radar and sensor fusion systems.
This training series provides an overview of the evaluation and development platforms as well as getting started with the software and development tools offered by TI on the Jacinto TDA2/TDA3 processors.
