The single-channel INS1001DE is intended to supply fast powerful voltage-regulated waveforms to the gates, which are extremely sensitive to over-voltage stress. Its output pulse amplitude is set by a low-drop-out regulator using two resistors, to, for example 6V which is commonly specified for enhancement-mode GaN hemts (diagram below right). A separate internal LDO provides 5V […]
The S32 CoreRide platform brings together NXP’s S32 compute, networking, system power management and ready-to-deploy software from the company’s extensive software partner ecosystem. The company is also unveiling its first S32 CoreRide solution for central compute based on NXP’s new S32N family of vehicle super-integration processors. It offers safe and scalable combinations of real-time and […]

Part 1 of this article addressed current shunts and Hall-effect sensor designs. This part discusses current transformers and new technology options such as magnetoresistance and even diamond quantum sensors. One of the major issues in today’s electric vehicles (EVs) is the ongoing evolution of technology with the standards evolving as well. In the 100+ years […]
The need to transition from gasoline and diesel (fossil fuels) powered vehicles to electric vehicles (EVs) to reduce carbon dioxide levels has revealed many controversial issues. Common issues include implementation timing, required infrastructure (including fast-charging multi-vehicle systems), legislated rather than consumer-based adoption, ongoing system enhancements, and sources of new critical raw materials. One of the […]
Taking D3I4080Y as an example, it operates from 4 to 8GHz and can handle average forward inputs up to 30W, peaking at 50W. Maximum reverse input power is 2W. “The component provides more than 16dB of isolation and has an insertion loss of less than 0.4dB,” said the distributor, Body size is 1 x 1 […]
Called TLP3412SRLA, it draws 6.6mA at the nominal operating voltage of 1.8V. Inside is a single Form-A (normally-open) ac or dc contact that can handle 48V, or 400mA continuously, or 1.2A pulsed. On-state resistance is typically 1Ω and it switches on-off in 350 and 150μs respectively. Isolation voltage is at least 500Vrms. Operation is up […]
1mΩ is at 50A 25°C with 5V on the gate, and rises to ~1.8mΩ at the max operating temperature of 150°C (minimum is -40°C). The preliminary data sheet has no maximum Rds(on) figures – Electronics Weekly has requested this information. The 0.65mm tall package is designed to dissipate heat through the PCB as well as […]
Water molecules and electron density corresponding to the exciton state resulting from photon absorption. Credit: Krystian Tambur (background)/Alexey Tal (water molecules) There is no doubt that water is significant. Without it, life would never have begun, let alone continue today—not to mention its role in the environment itself, with oceans covering over 70% of Earth. […]
