Pickering Interfaces has turned to mems relays from Menlo Micro for a PXI fault insertion tester that can simulate issues in high-speed Ethernet protocols up to MultiGBASE-T1. “Capability limitations mean that the high-speed bandwidth requirements of the latest MultiGBASE-T1 protocols cannot be supported with reed relays or electromechanical relays, dictating the use of mems switches,” Pickering product manager Steven Edwards. ...
The Ultra ECDP (electrochemical deplating) tool is designed specifically for wide bandgap compound semiconductor manufacturing, said ACM Research. It delivers uniform processing outside of the wafer pattern area with minimal undercut for high-precision wafer level gold (Au) bump, thin film and deep hole deplating. Gold exhibits high conductivity, corrosion resistance and malleability and is emerging as an advantageous material for ...
The use of SiC devices is branching out beyond EV traction drives, observes Jianfu Fu. SiC (silicon carbide) power devices are being increasingly widely adopted in electric vehicle (EV) traction drives. In tandem, in the push for greater usability and convenience, new generations of devices are enabling SiC’s advantages to spread to other high-voltage and high-power loads throughout the vehicle. ...
Arm has contributed a vendor-neutral version of its Foundation Chiplet System Architecture (FCSA), to the Open Compute Project (OCP) under its permissive open licensing policy. As vehicles integrate ADAS, centralised domain controllers and in-cabin experiences, the underlying compute requires datacentre class performance. FCSA is designed to provide the entire ecosystem with universal standards for chiplet integration. FCSA is ISA-neutral. Any ...
Vishay is offering 50W thick-film resistors in TO-220 packaging for mounting directly onto heatsinks. “Engineered to ensure reliability and durability in the most extreme automotive environments, the LTA 50 withstands high humidity conditions and temperatures to +175 °C, while providing tolerance against vibration and electrical stress,” according to the company. Minimum temperature is -55°C, and qualification is to AEC-Q200. Resistances ...
Melexis has brought out a dual-input inductive sensor integrated circuit (IC). The device simultaneously processes signals from two sets of coils to compute differential or vernier angles on-chip. This sensor is designed for automotive applications, particularly in systems such as steering torque feedback, steering angle sensing, or steering rack motor control (including steer-by-wire implementations). The increasing complexity of vehicle control ...
Toshiba has created a range of automotive-grade Zeners for surge protection in the 0.8 x 1.6mm SOD-523 package. Called the XCEZ series, they rated at 150 or 300mW (see below) and come in 20 E24 values between 5.6 and 36V. “With the electrification in the automotive industry, there is a growing necessity to prevent malfunctions caused by electrical noise,” the ...
Heavy rain in the Phoenix and Scottsdale areas of Arizona brought chaos to the roads and Waymo vehicles to a standstill. At the end of September, heavy rainstorms, accompanied by lighting and hail meant several rainfall in a short period of time. The city’s Waymo vehicles, used to driving in the warm, dry climate of the desert region, did not ...
As 800V high-voltage platforms become the new standard in electric vehicles, inverter systems are demanding capacitors with stronger high-frequency performance. Traditional aluminum electrolytic capacitors, limited by high ESR and poor frequency response, often cause DC bus voltage surges, reduce system efficiency, and restrict the performance of SiC-based devices. (Schematic diagram of the location of the DC-Link capacitor in the inverter, ...
TÜV SÜD has ASIL certified two RISC-V processors for ISO 26262 automotive functional safety: Codasip’s L735 up to ASIL-B, and its L739 up to ASIL-D. “In addition to functional safety certification, both products are also compliant with ISO/SAE 21434, the international standard for cybersecurity in automotive development,” according to Codasip. Both cores have a multi-issue in-order microarchitecture. L735 includes error-correcting ...
