The Thunderbolt Alternate Mode allows the two sides of a USB Type-C PD connection to discover, negotiate, and enter the Intel Thunderbolt 3 mode allowing transfer of high-speed data. The mode is negotiated using USB Power Delivery messaging, as listed in the USB PD specification. This application report explains the standard implementation of the Thunderbolt Alternate Mode and how it can be used with the Texas Instruments TPS6598x family of USB Type-C and USB PD controllers and associated software tools.

This application note includes an object versus range table to list the detection range capabilities of TI’s mmWave radar sensors. The method used for data collection is reported and the data for the maximum range recording for each objects is provided. Intuitions that can be gained from the table regarding radar cross section and maximum range detection are included.

Digital Input receivers are used in AC and servo motor control to interface various 24-V signals to the control module of the drive. These signals include inputs from field sensors and switches, position and speed feedback encoded as 24-V signals, clock or PWM inputs for speed control, and emergency stop signals, such as Safe Torque Off (STO). Isolation is used to manage ground potential differences.

A recent trend has been seen in appliances (both large-home and small-home appliances) for moving from high-voltage (HV) motors to low-voltage (LV) motors for low power application (<100-W). This transition is due to availability of low power drivers which have the following advantages over high voltage systems.

A common need of any system is controlling multiple devices through digital logic. Systems continue to move to lower voltage nodes for power savings. With this trend, using devices that are not natively compatible with the control logic of the system can lead to extra system costs through board size and BOM count. Also, the use of more components in the design of the system creates more opportunities for power sequencing issues. Using devices that have integrated support for the control logic of the system achieves a cost effective solution.

This application report describes the video processing performed by the DLPC230-Q1 as part of the DLP5531-Q1 chipset to display an image optimized for automotive light control applications such as high resolution headlights and other exterior lighting products. Topics include image sequencing, illumination driving architecture, dithering, gamma correction, and image resizing which all impact the final output image. This information is intended for system designers involved in video content generation and illumination design.

TI applications engineers and software tools typically configure the parameters required to optimally display video in automotive light control end applications. However, an understanding of these background concepts can benefit designers working with the DLP® Products chipset.

Time-sensitive networking (TSN) is an Ethernet extension defined by the Institute of Electrical and Electronic Engineers (IEEE) designed to make Ethernet-based networks more deterministic. Industries like automotive, industrial and performance audio use real-time communication with multiple network devices and will benefit from the TSN standard.

The consumer and enterprise world of Ethernet and wireless Ethernet communication is bandwidth oriented. For example, while browsing the Internet you accept a varying amount of delay before video playback starts. Although there is a preference for quick interaction, for the average user it is acceptable if one out of 100 clicks perform an order of magnitude worse. However, if a video is bad quality or even halted the typical consumer will be frustrated.

Even infrequent delays are unacceptable in control systems such as those inside automobiles, production lines or concert halls. The most important aspects for these systems are latency and jitter or variation in the latency of control data through the network. The maximum time a packet takes to reach the destination in the system defines the communication cycle or control frequency in the network.

The LM63615-Q1 is a synchronous buck converter with a wide input voltage range from 3.5 V to 36 V and maximum output current of 1.5 A.

The LM63615-Q1 can be configured as an inverting buck-boost (IBB) converter with a negative output voltage.

This application note demonstrates how the LM63615-Q1 can be used as an inverting buck-boost converter, along with optional design considerations for inverting buck-boost converters such as a PGOOD or EN level-shifter.

If higher output current is required, the LM63615-Q1 is pin-to-pin compatible with the 2.5-A rated LM63625-Q1 and the 3.25-A rated LM63635-Q1.

The LM63615-Q1 is also pin-to-pin compatible with 1-A rated LM63610-Q1.
