Toshiba Corporation’s (TOKYO: 6502) Semiconductor & Storage Products Company launched a high-side N-channel power MOSFET gate driver with built-in reverse battery protection functions for use in automotive applications such as idling stop systems. Mass production will start from September 30.
Idling stop systems, which turn off car engines while the car is stopping for traffic lights and traffic jams, are now commonly used in automotive systems as a means to improve fuel efficiency.
The new TPD7104AF gate driver and an N-channel power MOSFET forms a semiconductor relay for each power supply line to control the power supply between the batteries and the starter generator used in idling stop systems.
Vishay Intertechnology, Inc. (NYSE: VSH) expanded its IHLD series of low-profile, high-current dual inductors with a new device in the 3232 case size. Offering a high operating temperature range to +155 °C, the automotive-grade IHLD-3232HB-5A saves board space by combining two inductors in one 9.75 mm by 9.14 mm package.
The Vishay Dale inductor is optimized for automotive and commercial class D amplifier circuits, where the device reduces board space requirements and offers improved performance over multiple individual inductors. In addition, the IHLD-3232HB-5A is designed for excellent inductance stability over temperature and DC current, providing high-quality sound and low harmonic distortion due to linear saturation performance. The inductor pair is designed with very low coupling for minimal crosstalk between inductors.
BorgWarner supplies Eco-Launch™ stop/start accumulator technology and multi-segment wet friction plates for the new 8-speed rear-wheel drive automatic transmission (8L45) from General Motors.
To enable the transmission’s stop/start functionality, BorgWarner’s Eco-Launch hydraulic accumulator and solenoid valve are said to provide rapid, quiet and smooth engagements during engine restarts.
BorgWarner’s friction plate technology reduces drag and enhances shift feel. Improving fuel economy up to 5 percent compared with similar 6-speed automatic transmissions, the 8L45 transmission will debut on the 2016 Cadillac CT6 and will also drive the 2016 Cadillac CTS and ATS.
Eaton announced its TVS2 Supercharger, which the company said improves vehicle manufacturers’ ability to deliver an optimal single boosted application. The device can also be paired with other boosting technologies to deliver compound boosting solutions for improved engine performance. The announcement was made at the 20th Supercharging Conference in Dresden, Germany.
“This latest innovation within our boosting portfolio delivers on the key areas that our customers have the most interest in, including efficiency, weight reduction, improved engine performance and the ability to better package supercharger devices within existing and future architectures,” said Brian Contat, product director, Boosting, Eaton’s Vehicle Group. “With the demand for greater engine efficiency and power density, products such as TVS2 are needed to satisfy the requirements of these future powertrains.”
Molex Incorporated introduces its ML-XT Sealed Connection System, a highly reliable, securely sealed solution that minimizes electrical failures in grueling commercial vehicle applications while delivering assembly cost savings to original equipment manufacturers and harness makers.
Rated IP68 and J2030 power-wash capable, the ML-XT system features a one-piece plug housing and seal design, which is permanently bonded using cutting-edge, two-shot LSR (liquid silicone rubber) molding technology. This ensures definitive and repeatable retention of the plug seal and prevents the seal from rolling during un-mating and mating to guarantee correct seal positioning. It also eliminates the risk of a lost or forgotten seal during installation and maintenance.
dSPACE and RWTH Aachen University have developed a new simulation environment for electrical energy storage systems that supports a broad range of physical battery characteristics.
Under the name “Toolbox Speichersysteme” (Energy Storage Toolbox), a new simulation model developed at the Institute for Power Electronics and Electrical Drives (ISEA) of RWTH Aachen was combined with a graphical user interface by dSPACE. The resulting solution makes it possible to realistically and conveniently simulate the electrical and thermal behavior of various battery technologies, supercapacitors and other electrical energy storage systems, according to their design and cooling systems.
Freescale Semiconductor introduced the MC33772 3- to 6-cell lithium-ion battery cell controller, expanding its portfolio of highly integrated solutions for reducing BOM cost, increasing operating robustness, and meeting stringent functional safety requirements for automotive and industrial battery systems.
Together with its previously announced MC33771 14-cell battery cell controller, the MC33772 expands Freescale’s hardware- and software-compatible battery cell controller portfolio to encompass a full range of single chip, 3- to 14-cell solutions.
Elektrobit (EB) announced that it is working with Infineon Technologies (FSE: IFX / OTCQX: IFNNY) and NVIDIA to make it easier for the automakers and their suppliers to create advanced driver assistance systems (ADAS) that integrate the highest levels of safety. Together, the companies say they are delivering a first-of-its-kind solution that represents a powerful development platform for automated driving.
