More than 1,000 leak tests are performed on the average car and its components before a vehicle rolls off a final assembly line and into a new-car showroom. Fuel, brake and other critical safety systems are tested multiple times for leaks, as well as driveline components, fluid containers and wheels.
An increasing number of leak tests are conducted with hydrogen-based leak detectors, which are less expensive than helium-based systems and significantly better than more traditional water and pressure-decay methods, according to Thomas Parker, North American automotive sales manager for INFICON, a global supplier of leak-detection systems.
VectorCAST Integration Provides Ada Developers with Tools for Automated Code Review and Validation
Vector Software has integrated its VectorCAST test automation platform with CodePeer 3.0 – AdaCore’s advanced static code analysis tool for Ada, including version 2012.
VectorCAST and CodePeer now provide Development and QA teams with the ability to focus test efforts in areas most susceptible to errors. An additional capability allows developers of legacy applications the ability to augment code covered during unit/integration and system test with code considered “clean” by CodePeer.
Vishay Intertechnology, Inc. (NYSE: VSH) released new bidirectional symmetrical (BiSy) ESD protection diodes in the compact SOT-323 package.
Measuring only 2.3 mm by 2.1 mm with a low 0.95 mm profile, the space-saving Vishay Semiconductors single-line VLIN26A1-03G and dual-line VCAN26A2-03G offer low capacitance and leakage current for the protection of automotive data lines against transient voltage signals.
Diodes Incorporated New Hall Effect Latch Features Wide Range of Sensitivity Options for Automotive Applications
Such uses include commutation, encoding and position control of the various motors, pumps, fans and valves found in vehicle cabins for operating windows, sun roofs, seats, tailgates and air-conditioning.
These Hall effect latches can also be used in the engine bay for steering and sensing the speed and position of the crankshaft, camshafts, cooling fans, and water, oil and fuel pumps.

AVX Corporation has extended its high temperature AT Series MLCCs (Multilayer Ceramic Chip Capacitors) with two new case sizes (0603 and 0805), two new voltage ratings (16V VHT 250°C and 25V VHT 200°C), and new C0G and VHT temperature coefficients that differentiate the 200°C parts from the industry-leading 250°C parts.
Designed to accommodate emerging demands for capacitors capable of high-reliability, long lifetime performance at operating temperatures in excess of the current 125°C requirement, AT Series capacitors are the only high temperature MLCCs with reliability test data at 250°C, and are rated at both 250°C and 200°C to provide engineers with optimal derating schemes.
Newest 1/3-inch 1 megapixel sensor delivers significant improvements in low light signal-to-noise ratio, visible light sensitivity and infrared performance
ON Semiconductor (Nasdaq: ON) is expanding its 1/3-inch 1 megapixel (MP) image sensor portfolio with early sampling of the company’s first backside illuminated (BSI) sensor technology for the automotive imaging market.
The new sensor technology delivers 4x better low light signal-to-noise ratio, a 40 percent increase in visible light sensitivity, and greater than 60 percent improvement in near infrared (NIR) performance than the current market leading AR0132AT CMOS image sensor for advanced driver assistance systems (ADAS).
The firm said the probes provide superior performance and meet specific industry test needs per the latest industry standards. Like the existing 1 kV safety-rated HVD310x probes, these new probes are said to provide excellent performance by offering the best gain accuracy, widest differential voltage range, high offset range and exceptional common-mode rejection ratio (CMRR).
STMicroelectronics Automotive CAN ESD Protection Devices Are Compliant with All Key Interface Protocols
STMicroelectronics has introduced two new devices that combine superior protection of CAN (Controller Area Network) bus lines against electrostatic discharges and other transients and market-unique compliance with all key automotive interfaces.
The ESDCAN02-2BWY and ESDCAN03-2BWY are automotive-grade dual-line Transil™ devices that leverage ST’s long-term leadership in transient protection devices and its deep understanding of the automotive market.
The unique combination of parameters, including an ultra-low capacitance of 3.5pF and 24V minimum stand-off voltage, has produced what STMicro believes are the world’s first CAN protection devices to comply with all major interfaces, including CAN-FD, LIN, FlexRay, MOST, and SENT.
Texas Instruments (TI) (NASDAQ: TXN) introduced what it said is the industry’s fastest 120-V automotive grade half-bridge gate driver with robust handling features.
The driver, UCC27201A-Q1, provides a propagation delay at 15ns with short rise and fall times and the tightest delay matching of 1ns for 12-V to 48-V DC/DC power supplies. The UCC27201A-Q1 high-side/low-side gate driver offers advanced noise tolerance, resulting in improved overall system performance for hybrid vehicles.
