Variable-speed motor drive controller includes ARM Cortex-MO core
Infineon Technologies AG is releasing the new IMC300 motor controller series. It combines the iMOTION Motion Control Engine (MCE) with an additional microcontroller based on the Arm Cortex-M0 core. IMC300 complements the IMC100 series and aims at variable speed drives that require very high application flexibility. Both families, IMC100 and IMC300, share the same implementation […]
Super-small PTC thermistors target over-current protection tasks in consumer electronics
Murata Manufacturing has succeeded in commercializing the world’s smallest PTC thermistor (commonly known as a resettable fuse) in the 0201-inch size (0.6×0.3×0.3mm) for mobile devices, and has recently begun mass production of this device under the part number PRG03BC181QB6RL. As smartphones and mobile devices become increasingly multifunctional and more compact, demand is growing for smaller […]
Compact shunt resistors handle 4-W current detection tasks
Rohm recently announced the availability of shunt resistors, GMR50 series, delivering industry-leading 4W rated power (at electrode temperature TK=90°C) in the compact 5.0mm×2.5mm (2010 type package) size. It is ideal for current detection in motors and power supply circuits used in automotive systems and industrial equipment. This new series combines a revised electrode structure with optimized […]
Battery-management IC extends driving range, reliability, and safety of EVs
STMicroelectronics has revealed new battery-management technology that increases reliability, safety, driving range, and cost-effectiveness of electric vehicles (EVs). EVs are predicted to reach cost parity with conventional combustion-engine vehicles before the end of this decade and overtake in sales volume by 2038. ST, leveraging its technical capabilities to help carmakers achieve these goals, has announced an […]
Thermal propagation triggering and mitigation in medium- and large-format battery modules
by Iris Su, Project Engineer II, Inventus Power A recent change in Li-ion battery pack safety is the shift from a focus on just prevention to one that emphasizes prevention and mitigation. Battery pack designers who were once focused on preventing thermal runaway (TR) are now taking increasing measures on preventing single cell failures within […]
Tiny linear thermistors offer 50% higher accuracy, high sensitivity, single-point calibration
Texas Instruments expanded its temperature sensing portfolio to include linear thermistors that deliver up to 50% higher accuracy than negative temperature coefficient (NTC) thermistors. The higher accuracy of TI’s thermistors enables operation closer to the thermal limits of the other components and the overall system, helping engineers maximize performance while reducing bill-of-materials (BOM) and total […]
Miniature dc-dc converters target industrial apps with 1-W output
Flex Power Modules introduces new families of miniature DC-DC converters for industrial applications: the PUA-A, PUC-B and PUB-M. The new devices are all isolating converters providing output power of up to 1W, with no minimum load required. Efficiency is typically 84% (PUA-A), 80% (PUC-B) and 81% (PUB-M) – all at full load. Input-to-output isolation voltage […]
