Field-oriented control, also known as vector control, is a calculation-intensive algorithm for motor control which is now practical due to advances in ICs; it offers improved efficiency along with superior control of torque and other performance parameters. Motor control—and doing so accurately and efficiently—is a topic of great interest. Field-oriented control (FOC), sometimes called vector […]
Synthesized tuning, Part 2: Advanced synthesizers and performance
Part 1 of this FAQ looked at the basic issues and topologies related to the challenge of frequency synthesis. Part 2 continues with advanced approaches and their attributes, as well as general concerns when choosing a synthesizer. Q: Are there other digitally-controlled synthesizer topologies? A: Yes. A widely used one is called the classical phase […]
Heat sinks, Part 1: Thermal principles
A heat sink is a non-electronic, passive mechanical component that has a vital role in the reliability and performance of ICs, PC boards, modules, chassis, and more. Heat sinks often don’t get much attention, at least not in the early stages of a design. This FAQ will look at the basic thermal principles of these […]
Synthesized tuning, Part 1: Basic frequency-synthesizer principles
Frequency synthesizers of various architectures, made possible by IC technology, are a key building blocks for applications which must accurately tune multiple channels, and hop from one frequency to another while using a single signal source such as a crystal oscillator. When you want to tune a desired radio station — AM or FM — […]
60 GHz Radar on Module targets industrial automation applications
Mistral Solutions announced its USB-powered, production-ready 60GHz Radar on Module [RoM] for industrial automation applications. The 60GHz RoM is a highly-integrated ultra-compact solution based on TI’s newly launched IWR6843 Antenna on Package (AoP) chipset. Mistral’s 60GHz small form factor RoM is among the first Industrial Radar Modules based on Texas Instruments IWR6843 Antenna on Package […]
Antenna and board design incorporate 60 GHz mmWave sensors
Ainstein announced an antenna and board design for 60-GHz mmWave radar over-the-door sensors (ODS) using Texas Instruments’ IWR6843 family of devices. With Ainstein’s innovative radar system design, customization, and manufacturing capabilities, building automation designers can now leverage TI’snew 60-GHz mmWave sensors in overhead mounting positions for highly customized applications. This combination enables near real-time decision-making and signal […]
Image gallery: Smart, small, and integrated at electronica 2018
Over 80,000 attendees from 80 countries spent four days at electronica 2018 in Munich last month combing 17 halls, 182K square meters of exhibition space, and meeting with as many of the 3,100 exhibitors as possible. The driving force for many of the new products introduced at the trade fair was, again, the need to […]
Tiny precision data converters cover 14 thru 24-bit resolution ranges
Texas Instruments introduced four tiny precision data converters, each the industry’s smallest in its class. The new data converters enable designers to add more intelligence and functionality, while shrinking system board space. The DAC80508 and DAC70508 are eight-channel precision digital-to-analog converters (DACs) that provide true 16- and 14-bit resolution, respectively. The ADS122C04 and ADS122U04 are […]
12-bit, 29-kHz RGB LED drivers boast 29-kHz dimming frequency
Texas Instruments introduced a new family of LED drivers with integrated, independent color mixing, brightness control and a power-saving mode. The LP5018, LP5024, LP5030 and LP5036 enable smooth, vivid color and reduce system power consumption. The devices are the industry’s first to offer a 29-kHz dimming frequency, above human-audible range, to help designers of applications […]
Power management ICs, part 2: PMIC implementations
The power management IC (PMIC) is often a vital part of the lower-voltage DC subsystem, as circuits have multiple power rails with tight individual specifications as well as mandated relationships among them. Part 1 of this FAQ discussed the need for, PMICs and their general characteristics. Part 2 now looks at specific ICs which implement […]
