Allegro MicroSystems, LLC announced a new Vertical Hall-effect Sensor IC that the company said is an extremely temperature-stable and stress-resistant magnetic sensing device ideal for harsh operating environments.

Allegro’s A1260 is actuated by alternating north and south polarity magnetic fields in plane with the device’s branded face rather than perpendicular to the branded face, as in a traditional Hall-effect sensor. This enables system designers to achieve new mechanical configurations not feasible with traditional planar Hall sensors, including replacing through-hole SIP devices with tiny surface-mount SOT23 ICs, saving space and cost.

HELLA is introducing a new generation of its 24GHz radar-based driver-assistance technology.

With production starting in June 2015 at HELLA’s U.S. manufacturing plant in Flora, Ill., HELLA is launching their new generation 3.5 radar sensor system as a complement to its generation 3.0 system, which has been in production since last year.

Exit Alert
In addition to blind spot detection, lane change assist, rear cross traffic alert and rear pre-crash functionalities, which are already in series production, HELLA’s new system adds a fifth function to the OEM’s safety portfolio. The exit alert function is currently in pre-production status and ensures the safety of all road users; pedestrians, cyclists and other vehicles when exiting the car.

Toshiba Adds Motor Driver IC For DC Brushed Motors In Vehicle Engine Applications

June 26, 2015  by  

toshiba 6-26-15 6719A_HRESToshiba America Electronic Components, Inc. (TAEC) announced a small-sized motor driver IC for DC brushed motors used in vehicle engine applications such as electronic throttles and valve controls.

The new TB9051FTG, housed in a small, flat 6mm x 6mm P-QFN28 package, employs double-diffused MOSFET (DMOS FET) transistors as driver circuits.

As with its recently announced line of DMOS FET transistor arrays, Toshiba selected DMOS FET devices for the TB9051FTG driver circuits. As these devices do not require base current biasing, they have virtually no input current, which lets them process high current density per device area with low on-resistance. This enables low output voltage drop – in turn, allowing the new motor driver IC to operate with a high degree of efficiency.

Devices Offer Stability of Temperature Characteristic of ≤ 0.1 % for Automotive Electronics

Vishay Intertechnology, Inc. (NYSE: VSH) announced a new AEC-Q200-qualified version of its PTS series platinum SMD flat chip temperature sensors.

Designed to provide accurate and stable temperature sensing for automotive, space, and industrial electronics, Vishay Beyschlag PTS AT series devices combine enhanced thermal cycling performance with higher operating temperatures to +175 °C.

Thanks to a highly controlled platinum thin film manufacturing process, the new sensors offer an outstanding stability of temperature characteristic of ≤ 0.1 % after 1,000 hours, ensuring precise and reliable operation even under harsh conditions. Typical applications for the devices include A/T controllers, oil quality/level sensor modules, and ARS controllers.

AVX Adds Tantalum SMD Capacitors

June 24, 2015  by  

avx 6-24-15 AVV929 TMJ S1gma Series Tantalum Capacitors PRAVX Corporation has added more than a dozen new high-reliability SMD tantalum capacitors to its TMJ S1gma™ Series, which the company said exhibits the lowest DC leakage current (DCL) and twice the reliability of other commercial grade tantalum capacitors currently on the market (0.005CV standard and 0.001CV on selected codes).

AVX said the capacitors also have a baseline part failure rate of < 0.5% per 1,000 hours at 85°C and rated voltage.
