Standard LED cooler supports high bay lighting demands MechaTronix has released the company’s first standard high bay cooling platform with the ModuLED Mega passive LED cooler. In a diameter of 134 mm, a height of 100 mm and a weight of 1.5kg, the passive LED cooler keeps luminaires up to 10.000 lumen on the required case and junction temperature. With a thermal resistance Rth of 0.6 K/W the ModuLED Mega 134100-HBG can cool down 80 watts dissipated power or the equivalent of 115 watts electrical power. The ModuLED Mega is designed in such a way that afterwork like drilling holes or tapping screws threads can be avoided in the design. On one side there is a standard mounting pattern for direct assembly of the Mean Well HBG-60 and HBG-100 high bay LED driver. The other side of the cooler has a typical modular ModuLED design, with a variety of mounting patterns for each Zhaga LED module and the top 15 LED manufacturers of COB LED engines. An example of a high bay sub assembly with the Mean Well HBG-100 LED driver, ModuLED Mega 134100 LED cooler, Laird TPCM phase change thermal pad, Cree CXA3070 COB module and BJB Zhaga LED holder. The ModuLED Mega is an example of the ideal balance between conduction, convection and radiation cooling and guarantees by this an optimal performance to space ratio. Besides the 100mm high model for high bay designs, the LED cooler will also become available in a limited height of 20 mm with a cooling performance up to 4000 lumen. MechaTronix www.led-heatsink.com Precision Hall-effect angle sensor SoCs for automotive and industrial Allegro MicroSystems’ A1332 and A1334 are high-resolution 360° angle sensor ICs based on magnetic circular vertical Hall (CVH) technology. These contactless Hall-effect magnetic sensors, with their systemon chip (SoC) architectures, provide high output refresh rates and low signal-path latency to support a variety of demanding automotive and industrial applications. Both devices are suitable for automotive applications such as electronic power steering (EPS) and transmission systems, and for sensing motor position, throttle/pedal position, and other parameters that require the accurate measurement of angles. The A1332, with an onboard 32-bit processor and EEPROM for factory and customer programmability, includes segmented and Fourier linearisation functions for supporting challenging off-axis/ side-shaft magnetic sensing configurations that are commonly found in electronic power steering and transmission applications. The A1332 also supports on-axis/end-of-shaft magnetic sensing configurations, and can produce highaccuracy angle measurements with an output refresh period of 32s. The device incorporates a 2-wire IC digital interface with signal path and I/O diagnostics for achieving higher reliability to meet ASIL automotive safety requirements. The A1334, with its onboard digital signal processing functions and EEPROM for factory and customer programmability, is designed specifically for on-axis/end-of-shaft applications that require ultra-fast output refresh rates and low signal path latency. Its 4-wire 10 MHz SPI interface offers a 25s output refresh period and a nominal signal-path latency of 60s. Allegro MicroSystems BOD2 adapter, app bring the repair www.allegromicro.com shop to the tablet The EasyDiag Plus adapter from Launch Europe connects a tablet computer or smartphone to the on-board diagnostics Solid state relay switches through optical command Avago Technologies’ ACPL-K30T is claimed to be the industry’s first solid state photovoltaic driver to be automotive qualified per AEC-Q100 Grade 1. The device features high ESD rating and fast turn-off time (40 μs typical) and is compatible with a wide selection of AEC-Q101 certified MOSFET components to form a solid state relay solution of desired voltage or current rating. Because the part is optocoupler-based, switching off the LEDs on one side of the part totally cuts off the drive voltage on the other side of the device, making it optimized for use in battery management systems of modern electric vehicles (EV), hybrid electric vehicles (HEV) and plug-in hybrid electric vehicles (PHEV) as well as high-temperature power systems of conventional internal combustion engine vehicles. The part’s open circuit voltage is 7V (typical at a LED drive current of 10mA), and short circuit current is 5μA. It comes in a stretched SO-8 package compatible with standard surface mount processes, Lead(Pb) free and fully RoHS 6 compliant.

In addition it supports specific interactions with ECUs such as ABS/SRS, Airbag, or transmission controller. The EasyDiag Plus adapter connects to the handheld device via Bluetooth; the related app (available for Apple and Android) can be downloaded free of charge from the adapter vendor. The software provides a vehicle-specific in-depth analysis for two vehicle brands without cost; additional brands can be downloaded against the payment of a fee. This analysis allows users to look deeply into software and control systems of the respective vehicle. Besides this analysis, the adapter supports standard OBD-2 and EOBD diagnosis for all brands and displays real-time data. In addition, the EasyDiag Plus contains software that allows users to look into the engine management functions, enabling him to check OBD error codes or read out data like engine coolant temperature.
