Linear Technology announced the LTC6804 high voltage battery monitor for hybrid electric and electric vehicles, and other high voltage, stacked-battery systems.  

An LTC6804 can measure up to 12 series connected battery cells at voltages up to 4.2V with 16 bit resolution and better than 0.04% accuracy.  This high precision is maintained over time, temperature and operating conditions by a sub-surface Zener voltage reference similar to references used in precision instrumentation.  When stacked in series, the LTC6804 enables the measurement of every battery cell voltage in large high voltage systems.  Six operating modes are available to optimize update rate, resolution and the low pass response of the built-in 3rd order noise filter.  In the fastest mode, all cells can be measured within 290µsec.

Multiple LTC6804s can be interconnected over long distances and operated simultaneously, using Linear Technology’s proprietary 2-wire isoSPI  interface.  Integrated into every LTC6804, the isoSPI interface provides high RF noise immunity up to 1Mbps and up to 100 meters of cable, using only twisted pair.  Two communication options are available: with the LTC6804-1, multiple devices are connected in a daisy chain with one host processor connection for all devices;  with the  LTC6804-2, multiple devices are connected in parallel to the host processor with each device individually addressed.

The LTC6804 was designed to minimize power consumption, especially during long-term storage where battery drain is unacceptable.  In sleep mode, the LTC6804 draws less than 4µA from the batteries. General purpose I/O pins are available to monitor analog signals, such as current and temperature, and can be captured simultaneously with the cell voltage measurements.  Additional features include passive balancing for each cell with a programmable balancing timer for up to 2 hours, even when the LTC6804 is in sleep mode.  The LTC6804 interfaces with external I2C devices such as temperature sensors, ADCs, DACs and EEPROM.  Local EEPROM can be used to store serialization and calibration data, enabling modular systems.

The LTC6804 was designed to surpass the environmental, reliability and safety demands of automotive and industrial applications.   The LTC6804 is fully specified for operation from -40°C to 125°C.  It has been engineered for ISO 26262 (ASIL) compliant systems and a full set of self-tests ensure that there are no latent fault conditions.  To accomplish this, the LTC6804 includes a redundant voltage reference, extensive logic test circuitry, open wire detection capability, a watchdog timer and packet error checking on the serial interface.

The LTC6804 is offered in a small 8mm x 12mm surface mount device.  Priced at $10.95 each in 1,000-piece quantities, samples, demonstration boards and the data sheet are now available at www.linear.com/product/LTC6804. 

A new interference test set and other enhancements to Tektronix’ BERTScope bit-error-rate testers and PCI Express test software give silicon, host, and card designers a powerful automated transmitter/receiver compliance and debug platform for the PCI Express 3.0 bus standard.

At speeds of 8 Gbps, PCI Express 3.0 testing involves complex receiver stress conditioning, BER compliance testing, and numerous transmitter compliance tests. According to Tektronix, its updated platform provides the industry’s most integrated level of support for physical-layer test automation and debug of PCI Express 3.0.

For PCIe 3.0 receiver testing, stressed pattern generation as required by PCI-SIG test specifications are automated and now include integrated support for clock multiplication and eye-opening tests. Additionally, DUT loopback control is automated. New tools that enable these capabilities include the DPP125C digital pre-emphasis processor, which adds pre-emphasis to the stressed pattern; the BSAITS125 integrated interference combiner with variable ISI (intersymbol interference); and the BSAPCI3 automated calibration, loopback, and link-training software.

The high incidence of returns and the consumers' desire to get help with their products presents a unique opportunity for retailers to intervene,” said Ben Arnold, director of industry analysis at NPD. Making sure the consumer knows how to use their new device, whether it be a smartphone or a PC, and knowing how to use it before they leave the store helps increase product and retailer satisfaction.”

An earlier study by NPD Group found a majority of consumers used tech support for troubleshooting and how-to-support, not for product repair, Arnold said. He added that this was more evidence that these devices are working but that consumers are having trouble operating them.

Retailers have an opportunity with exchanges to show consumers they can provide quality and value,” Arnold said. As technology devices become more complex and connected, pre-and post-sales support becomes more important in keeping returns low and consumer satisfaction for brands and retailers high.”

The study found that flat-panel TVs had the lowest incidence of return among consumer electronics products, roughly 4 percent, NPD Group said.Related stories:
