Q: Do automakers in general have the same set of priorities for “the connected car” or do their priorities differ?

A: At this stage of connected car evolution automaker priorities differ because they are in the process of working out the business objectives and strategic approaches for their programs.

Hydrogen-Based Leak Detectors Reduce Testing Time and Cost

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.

Diodes Incorporated New Hall Effect Latch Features Wide Range of Sensitivity Options for Automotive Applications

DI0828-AP3726-AP3796Q_Showcase_ImageThe AH376xQ family of AECQ100-qualified Hall effect latches introduced by Diodes Incorporated offers eight magnetic sensitivity options to cover the requirements of numerous 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.

Teledyne LeCroy Adds 2kV and 8kV Safety-Rated High Voltage Differential Probes

July 10, 2015  by  

TTELEDYNELECROY 7-10-15 _hvd3605_probeeledyne LeCroy introduced two new additions to the HVD3000 series of high voltage differential probes — the 2 kV safety-rated HVD3206 and the 8.4 kV safety-rated HVD3605.

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).

120-V High-Side/Low-Side Gate Driver Reduces Switching Loss; Minimizes Noise for Greater Efficiency and Longer Mileage

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.
