Freescale Semiconductor today announced availability of its one-cylinder (MC33813) and two-cylinder (MC33814) electronic control semiconductors for small internal combustion engines for transportation, industrial and consumer applications. These analog integrated circuits for small engine control reduce design complexity, bill of materials and manufacturing costs, while helping shorten the customer’s time to market. Reliability is improved ...

International Rectifier has launched the AUIRFR4292 and AUIRFS6535 automotive-qualified power MOSFETs featuring low on-state resistance (Rds(on)) for Piezo injection systems for both diesel and petrol engines.

ROHM Semiconductor has recently announced the development of the RBxx8 series of ultra-low IR Schottky barrier diodes capable of operating at high temperatures, enabling support for automotive and power supply devices. Power consumption is reduced by approximately 40% compared to conventional automotive rectifier diodes, making them ideal for energy-saving circuits in electric vehicles (EVs) and hybrid electric vehicles (HEVs).

Microchip announces the expansion of its serial SRAM portfolio with four new devices that feature the industry’s largest densities and speeds. They are also the industry’s serial SRAM first with 5V operation, which is used extensively in automotive and industrial applications. These low-cost 512 Kb and 1 Mb SPI devices maintain the portfolio’s low power consumption and small, 8-pin packages. Speeds of up to 80 Mbps are achieved via the q...

A growing number of USB ICs are keeping time using a 48 MHz basic sound frequency quartz crystal instead of a quartz oscillator. PETERMANN-TECHNIK offers an extremely inexpensive crystal along with a host of technical services.

Linear Technology Corporation announces the LT3959, a highly versatile DC/DC converter for boost, SEPIC and inverting power supply applications. This device operates over an input voltage range of 2.5V to 40V, has an onboard 6A/40V power switch and achieves efficiencies up to 96%, making it well suited for industrial, automotive, medical and telecom applications.

An automotive version of the A4950 full-bridge motor driver IC is now available from Allegro MicroSystems Europe. The A4950 is designed for pulse width modulated (PWM) control of DC motors, and is capable of peak output currents to ±3.5 A and operating voltages to 40 V. The device is AECQ100 Grade 1 qualified and is rated over an extended ambient operating temperature range of -40°C to 125°C.

International Rectifier has announced the introduction of a family of automotive-qualified 600V IGBTs for electric and hybrid vehicle applications including air conditioner inverters, pumps and Positive Temperature Coefficient (PTC) heaters.

ROHM has developed the BD7xxL2EFJ-C series of high-voltage (50V) LDO regulators for automotive applications featuring the industry’s lowest dark current* (6μA) – 80% lower than conventional LDO regulators – utilizing a proprietary circuit design, reducing power consumption significantly.

Cypress Semiconductor Corp today announced that Traxxas, one of the leading providers of ready-to-run (RTR) radio controlled hobby vehicles, has selected Cypress’s WirelessUSB-LP 2.4-GHz radio-on-a chip for their new XO-1 radio controlled supercar.
