Interface device connects 5 CAN buses to one USB channel The Memorator Pro 5xHS from Swedish vendor Kvase AB eases the work of test engineers in automotive and industrial environments: The data concentrator connects multiple CAN buses to a data logger or similar downstream device through a single USB channel. What’s more, it synchronises the data transmitted and received across all five CAN buses - and it also synchronises with other Kvaser interfaces that are connected to the same PC. The Memorator has a 26 pin HD DSUB that connects to a splitter with five 9 pin DSUBs, and one USB connector that links to any USB port on a host computer. Only one USB port needs to be allocated when monitoring multiple CAN buses, reducing the need for an external hub in many applications. A special feature of the 5-channel Memorator Professional is its ability to run user scripts. Like other Kvaser’s products such the Eagle interface and data logger, the Memorator Pro 5xHS’s script functionality allows users to develop customised applications written in the Kvaser t programming language. Examples of such applications are CAN protocol converters and gateways as well as CAN logging functionality. Application-specific scripts for this device will also be available from Kvaser’s network of technical associates, who contribute their respective domain expertise. Kvase AB www.kvaser.com USB human interface design platform, provided as IP Polish IP Core provider and SoC design house Digital Core Design has assembled its USB HID Design Platform, a complete and integrated solution which targets almost all aspects of USB based Human Interface Devices. DCD is offering its product for Internet of Things (IoT) projects which the company says will benefit from its software stack with an ultra-low power DP8051 8-bit CPU. Digital Core Design’s USB HID Design Platform is a complete and integrated solution created to assist the USB-based Human Interface Devices design process. Mice, keyboards, tablets, and also hundreds of other devices, depend on a stable USB connection. A true programmable embedded system-on-chip integrating configurable analogue and digital peripheral functions, remains one of the biggest challenges engineers face, DCD asserts. Digital Core Design http://dcd.pl/ipcore/93/hid-platform/ 230ºC silicon power MOSFETs feature integrated drivers X-REL Semiconductor (France), fabless semiconductor specialist maker of devices rated for long-term operation at high temperatures, has added the XTR20410 and XTR20810 hightemperature families of N-channel Power MOSFET with integrated driver circuitry. These product families are intended for power conversion applications in highly demanding markets including aerospace, industrial, hybrid and electric vehicles, transportation, geothermal and oil and gas. The XTR20410 and XTR20810 product families consist of power N-channel MOSFETs and integrated drivers tailored for use in extreme reliability and high temperature applications, such as DC/DC converters, motor control and power switching. Matching network optimisation between a driver and a power transistor is, says X-Rel, a difficult and time-consuming task: these devices provide users with a turnkey solution that already matches power transistor and driver inside a single piece of silicon. XTR20410 parts may be used as high-side (40V max), low-side, or low-side switch with negative offset (-30V max) on the output stage (source connected to a negative voltage), while receiving a control input signal referred to GND. XTR20810 parts are intended to be used as low-side switches, and are able to sustain transient overshoot voltages up to 100V. Devices in the XTR20x10 families are able to reliably operate from -60°C to well above +230°C (5 years at +230°C). All X-REL Semiconductor products can be used in applications running at lower temperatures (e.g. from 100°C to 200°C) where extended lifetime is expected or where failing is not an option. For example, the expected lifetime of X-REL Semiconductor parts in an application operating at Tj=150°C is over 35 years. Parts from XTR20410 and XTR20810 families can be packaged in both niche and large-scale markets in high-reliability compact hermetic or plastic packages, as well as bare dice. X-REL Semiconductor www.x-relsemi.com Low capacitance TVS diode arrays support fast-charging peripherals Littelfuse, Inc., has introduced the SP1255P Series Low Capacitance ESD Protection TVS Diode Arrays (SPA Diodes), which are designed to provide superior ESD protection for current-intensive applications, such as fast-charging peripherals or PoweredUSB. The SP1255P Series integrates three channels of ultra-low capacitance steering diodes with a low voltage TVS diode to provide maximum ESD protection of the USB data and ID pins per the IEC 61000-4-2 standard. With a dynamic resistance of 0.3Ω, they provide clamping voltages up to 23 percent lower than similar silicon solutions. A high surge current protection device with a working voltage of 12 V is allocated for Vbus protection; this device protects against lightning level fast transients of up to 100 A on the USB Vbus line. Typical applications for the SP1255P Series include ESD protection for smartphones, tablets, and other portable electronics. The SP1255P Series arrays offer low dynamic resistance of 0.3Ω provides clamping voltages up to 23 percent lower than similar silicon solutions to offer superior protection for current-intensive applications such as fast-charging peripherals. The small form factor μDFN-6 package (1.8x2.0x0.55 mm) simplifies the PCB layout by allowing the traces to run directly underneath the device without the need for stub traces that can cause signal degradation. Automotive-grade quality (AEC–Q101 qualified) ensures maximum reliability in the harshest environments.
