Linear Technology announced the LTC6811 high voltage battery stack monitor, a drop-in replacement for the LTC6804 with higher performance and a 25% lower price.
The LTC6811 is a complete battery measuring IC for hybrid/electric vehicles that incorporates a deep buried Zener voltage reference, high voltage multiplexers, 16-bit delta-sigma ADCs and a 1Mbps isolated serial interface.
An LTC6811 can measure up to 12 series-connected battery cell voltages with better than 0.04% accuracy. With 8 programmable 3rd order low pass filter settings, the LTC6811 is said to provide outstanding noise reduction. In the fastest ADC mode, all cells can be measured within 290µsec.

Texas Instruments (TI) (NASDAQ: TXN) introduced what it said is the industry’s first smart diode controller with zero quiescent current. According to the company, the LM74610-Q1 provides better efficiency versus Schottky diodes and p-channel MOSFETs. It also provides lower power consumption and heat in a compact solution size, making it well-suited for reverse polarity protection in high-current industrial power tool and automotive applications.

Mentor Graphics Announces New FloTHERM Product with Automated Calibration for Package Model Accuracy
November 12, 2015 by John Day
Mentor Graphics Corporation (NASDAQ: MENT) announced the newest version of its FloTHERM® product, a powerful and accurate computational fluid dynamics (CFD) software solution.
The FloTHERM product was developed to quickly identify potential thermal issues early in the design process to avoid expensive late stage re-design and warranty costs arising from thermal failures in the field.

After a five-year development effort Trillium Inc., a small (12-person) Japan-based firm, is able to offer software-based security for CAN buses. It expects to offer the same for LIN and other communication topologies.
Trillium offers SecureCAN™ for encryption and Dynamic Key-Lock Pairing™ (DKLP), Trillium’s proprietary key management system, which is customized for protecting the automotive CAN bus.
SecureCAN uses TrilliumCipher™, which the firm describes as an ultra lightweight, symmetric block cipher with variable block size and key size. The cipher consists of three algorithms: Substitution, Transposition, and Time Multiplex.

The Bosch infotainment system that Suzuki is introducing in several models worldwide creates, according to Bosch, a connected information system that offers a broad range of infotainment and assistance functions aimed at meeting today’s demands for added value.
The system ensures that passengers in Suzuki vehicles can stay in constant contact with the outside world. The 7-inch color touch-screen displays connectivity options including smartphone integration via Mirror Link™ and Apple CarPlay®, advanced map navigation and voice control, a hands-free Bluetooth® system, and music via audio-streaming or “crystal-clear” radio reception with digital radio in Europe.

This optional software package enhances the standard capabilities of the Motor Drive Analyzer software by adding advanced harmonic filtering for AC Input and Drive Output Numeric table measurements; Total Harmonic Distortion (THD) measurement parameters for voltage, current, and power, and a new Harmonic Order table with Spectral waveform displays.
Advanced Harmonic Filtering
The standard Motor Drive Analyzer software provides either Full Spectrum (no harmonic filter applied) or Fundamental Only harmonic filters. The new option adds a Fundamental+N and a Range Filter. The Fundamental+N filter allows the user to specify how many (N) harmonics from the fundamental to include in the Numerics table calculations.
