New Products


Global manufacturer and supplier of connectors, interconnects, and cable assemblies ITT Interconnect Solutions has developed a miniature circular connector solution. Designated the KPTC series, the backshell connector provides high contact density in a rugged metal shell and was originally developed for a luxury car manufacturer and an associated subcontractor to accommodate specific harnessing requirements within automotive diagnostic equipment.

The KPTC series connector is capable of integrating custom harnessing rigs and a wide range of wire gauges. Additional features include IP67 sealing and gold-plated contacts, allowing the connector to withstand harsh environments, as well as bayonet coupling for quick and simple mating and unmating. A shielded endbell is available for fast assembly.

Offered in size 20 and size 16 contacts, the KPTC series connector features a lifespan to at least 500 mating cycles. Contact current rating at 20 °C is 7.5 A for the size 20 connector and 22 A for the size 16 connector. Contact resistance is 14.7 mOhms and 3.8 mOhms, respectively. Typical pricing for the KPTC series circular connector ranges from approximately $23 to $26 each. Lead time is six weeks.

Maxim Integrated Products has released highly integrated, 300 mA automotive linear regulators with a voltage tracker and load-dump protection. Designed to withstand harsh operating conditions, the new low-dropout (LDO) regulators, MAX15008/MAX15010, integrate robust protection circuitry; operate over a wide 5 V to 40 V supply-voltage range; and are able to withstand load-dump transients up to 45 V. To enable precise ratiometric tracking in automotive applications, the MAX15008/MAX15010 offer a tracked output voltage that is capable of delivering up to 50 mA to a remote sensor. The voltage tracker provides tracking accuracy within ±3 mV, as well as battery-reversal and short-circuit protection. The integration of robust protection features and voltage tracking makes these linear regulators ideal for automotive sensor applications, such as instrument clusters, climate control, and power-supply circuits.

The MAX15008/MAX15010 offer independent enable controls for the linear regulator, voltage tracker, and overvoltage protector (MAX15008 only) to optimize performance. Offering low power consumption, these linear regulators consume only 50 μA of quiescent current in a stand-alone configuration, and 20 μA in shutdown mode. Well suited for always-on circuits, these devices provide enable and hold inputs for key-off conditions. Additionally, to save cost and further improve performance, the MAX15008 integrates an overvoltage-protection (OVP) controller that protects downstream circuits from high-voltage load dump, thus allowing the use of lower-cost DC-DC converters. The MAX15008/MAX15010 are available in a thermally enhanced, 5 mm x 5 mm, 32-pin TQFN package, and are fully specified over the -40 °C to +125 °C automotive temperature range. Pricing starts at $1.45 in 1000 pieces and up.

OSRAM Opto Semiconductors has announced the Diamond DRAGON. Diamond DRAGON achieves brightness of up to 250 lumens, and will be available in whites ranging from 2700 K through 6500 K as well as all monochromatic colors. With this latest advance in technology, OSRAM will offer an LED that is ideal for indoor and outdoor general lighting, automotive forward and signal lighting, and other high-performance applications.

The low thermal resistance of Rth = 2.5 K/W provided by the Diamond DRAGON's SMT package allows heat produced in the chip to be efficiently removed from the LED package. The maximum junction temperature of 175 °C makes these LEDs extremely robust and enables applications where the LED cannot be easily cooled. The combination of low thermal resistance and high junction temperature capability allows Diamond DRAGON LEDs to be easily integrated in small spotlights such as MR-16's bulb retrofits, and recessed downlights.

The LEDs can withstand high drive currents without damage. Typical (binning) current is 1.4 amps, with a maximum current of 2.0 amps. 50,000 hours is the typical expected lifetime. This robust package incorporates a silicone lens and is fully SMT compliant. The Diamond DRAGON footprint is compatible with previous devices allowing upgradability for current Golden and Platinum DRAGON users.

This high-brightness single-chip device uses OSRAM's ThinGaN chip technology along with chip-level conversion. The new Diamond DRAGON is rated for 5-8 W input power and enhances OSRAM's large power LED portfolio that includes 1 to 3 W LEDs (Golden and Platinum DRAGON) as well as the 10 W and up line of OSTAR devices.

OSRAM development engineers have achieved new records for the brightness and efficiency of white LEDs in the laboratory. Under standard conditions with an operating current of 350 mA, brightness peaked at a value of 155 lm, and efficiency at 136 lm/W. In generating these results, researchers used white prototype LEDs with 1 mm-square chips. The light produced had a color temperature of 5000 K, with color coordinates at 0.349/0.393 (cx/cy).

The key to the company's success was the efficient interplay among all the advances made in materials and technologies. A perfectly matched system of optimized chip technology, a highly advanced and extremely efficient light converter, and a special high-performance package all combined to produce record performance results.

Potential applications for this high-performance LED technology include general illumination, the automotive sector, and any application that calls for large, high-power LEDs. These semiconductor light sources are also suitable for high operating currents. At 1.4 A, they can produce up to 500 lm of white light. This means that in the future the LEDs can also be used for projection applications as blue and green chip versions.

Renesas Technology America, Inc. has introduced the SH72544R 32-bit microcontroller (MCU), the newest member of the 32-bit SuperH RISC family. It enables the design of advanced electronic controls for car and truck engines and transmissions that boost efficiency, decrease emissions, and improve performance. Operating at speeds up to 200 MHz, the MCU achieves the 400-MIPS performance and the high reliability essential for next-generation automotive applications and has 2.5 Mbytes of on-chip flash memory for storing highly precise real-time control algorithms. It is available as a packaged device (272-pin P-BGA) specified for operation at 125 °C.

The many peripheral functions built into the new MCU meet the specific requirements of advanced engine and transmission control systems. Besides a multifunction timer (ATU-III: Advanced Timer Unit III), the SH72544R provides a fast multichannel 12-bit A/D converter, CAN interface, high-speed serial interface functions and multi-input signature generator. This high level of integration saves cost and allows compact controls that fit into tight spaces in engine compartments, transmission cases, etc.

The SH-2A superscalar 32-bit RISC CPU core of the SH72544R has the computing power needed to execute very fine-grained, high-level, real-time control of engine/transmission systems. Despite providing the large 2.5 Mbyte on-chip flash memory made possible by fabrication in a 90 nm process, the power-efficient MCU consumes less than 900mW, even when operating at 200MHz in +125 °C environment. Its flash capacity is 2.5 times that of the SH7058, sufficient for storing the larger application programs required to obtain performance improvements. Additionally, for data storage, the new MCU provides 128 Kbytes of flash memory with functions and endurance essentially equivalent to those of EEPROM. This eliminates the need for external EEPROM and thus reduces system costs.

Although flash memory generally has a slower maximum operating speed than digital logic circuits due to its operating principle, Renesas has applied unique technologies to increase the speed of the flash built into the SH72544R chip. Furthermore, the MCU incorporates a low-power cache system that optimizes the use of flash memory. The overall result is flash memory performance that is essentially equal to single-cycle access at 200 MHz.

Support for the new SH72544R MCU includes the previously mentioned SH72546RFCC device that facilitates software development. The SH72546RFCC differs by having a large-capacity emulation RAM for efficient debugging and allowing control parameters to be adjusted while it is operating.
