This training video discusses the strong gate driver introduced high dv/dt and di/dt during turn-on and turn-off switching transition, and also illustrate the high dv/dt and di/dt introduced noise through the parasitic capacitance/inductance on high side level-shift and junction capacitance on the bootstrap diode. Solutions with new state-of-the-art gate driver and its key features are introduced and explained.
This training video summarizes the content of this gate driver series and the key references.

New to mm-wave sensing? This series of five short videos provides a concise yet in-depth introduction to sensing using FMCW radars.
Labs are follow-along training videos that walk you through installation, building, and running example mmWave sensor projects.
This section covers the basics of mechanical water meters and the principle of operation for impeller based water meters. There are multiple standards for water meters around the world; the EN ISO 4064 is relevant to all European countries and has been adopted under a different name in some other regions as well.
Water and heat meters share multiple system building blocks, such as the metrology sub-system and the application sub-systems, the Wireless communications part, the InfraRed optical port or the power solution. In this section, we will cover a new ultra-low cost single-chip LC-sensing solution utilizing the CC1350 Wireless MCU and its Sensor Controller Engine. Two external LC-tanks with a TI FemtoFET device each implement two rotation detection sensors, which measure the rotation of a half-metal/half-nonmetal disc, often used in mechanical water meters.
Some EU standards like EN1434-3 for heat meters require optical interface as per EN62056-21, where two separate IR LEDs are used (one for receive and one for transmit direction). TIDA-01212 shows an alternative approach, which uses a single IR LED to implement a bi-directional IrDA PHY link with 9.6 kbps in half-duplex mode. The design approach can the system reduce cost of any smart (sub-)metering device by replacing the legacy optical IrDA PHY modules with two separate LEDs.
This module covers the “Innovative 7-Segment LCD Control Using GPIO Pins and SW” section of the “Single-chip Smart Water meter with Dual-band RF link and InfraRed port” training series.
In 2019 more than 2.5 million industrial robots will be in operation worldwide, according to a forecast of the international federation of robotics. An industrial robot typically consists out of a control cabinet, a robot arm and a Human Machine Interface (HMI) Panel. To guarantee safe operation of the complete robot system, the different robot components and its interfaces need to be isolated to each other.
The training starts with an overview of an analog input module. Typical components and their voltage supply levels are shown. Next, possible power topologies like push-pull, flyback or flybuck with their advantages and disadvantages are discussed.
CNC routers use step and direction signals to control each stepper motors. In addition motor information (position, temperature, fault) gets transferred from stepper motors back to control unit. This must be done in star topology and a mix of proprietary interfaces. Simple open real-time Ethernet (SORTE) enables 4 µs cycle time on industrial Ethernet and replaces step/direction signal and motor feedback info into a single Ethernet cable that is also wired in line topology.
