The first member of Micronas' second generation of embedded motor controllers comes up with a unique integration level and unprecedented flexibility
Freiburg, May 12, 2015 - Micronas announces today the first member of its new generation of embedded motor controllers HVC 4223F. The device is a key enabler for the design of efficient, compact and cost-effective electric motor applications not only in vehicles, but also in the industrial environment. Due to its integrated power bridges, the HVC 4223F comes up with an unprecedented level of integration and flexibility for the direct drive of BLDC, BDC and stepper motors packed into one single device with a footprint four times smaller than a stamp. Engineering samples of the HVC 4223F are available as of today.
The number of electric motors in a vehicle continues to increase and Automotive customers are paying more and more attention to the implementation of smart electronic actuators. Micronas provides an Automotive qualified all-in-one device for the efficient control of various electric motors. It enables the design of very small, efficient, silent and cost-efficient actuator solutions for applications such as HVAC flaps, active grille shutters, pumps, air cooling fans, mechanical actuators in bending lights, and many, many more.
"The small footprint of the only 6x6 mm leadless QFN40 package with a minimum of additional external components required as well as the low software invest reduces the cost-of-ownership for Micronas' customers significantly", says Dirk Behrens, Vice President Automotive at Micronas. "Together with its industry standard ARM Cortex-M3™ core and state-of-the-art development toolchain, the new motor controller device guarantees the efficient implementation of the customers' automotive qualified production software enabling a fast time to market."
Developed in a mixed-signal High-Voltage (HV) CMOS technology, the integration level of the HVC 4223F is unique in its kind. The various integrated digital and analog components include comparators with virtual star point reference, diagnosis and protection functions, programmable gain amplifier, A/D converter, embedded voltage regulators with up to 40 V load dump, as well as six identical half bridges to drive high currents. The HVC 4223F is designed to be directly connected to the motor windings without the need for external MOSFETs and furthermore can be directly supplied by the 12 V board net without the need for external voltage regulators. The internal LIN transceiver allows the direct connection to the LIN bus. On top, the ARM Cortex-M3 core facilitates the implementation of complex motor commutation schemes for an optimized size-torque ratio of the motor. This enables Micronas' customers the compact design of complex motor control applications.
Micronas presents the HVC 4223F from May 19-21 at the Sensor+Test exhibition in Nuremberg, Germany, at booth 302 in hall 12.

The Federal's pistol slid into its holster and his sabre flashed out. He threw its curved point up in a splendid salute. Ferry saluted with his straight blade. Then both swords rang back into their scabbards, and Jewett whirled away toward his column. For a moment we lingered, then faced to the left, trotted, galloped. Over the fence and into the road went he--went I. Down it, as we crossed, the blue column was just moving again. Then the woods on the south swallowed us up. "All right, sir." that before. Meanwhile the parallelism between Thought and Extension was not exhausted by the identification just analysed. Extension was not only a series of movements; it still remained an expression for co-existence and adjacency.412 Spinoza, therefore, felt himself obliged to supply Thought with a correspondingly continuous quality. It is here that his chief originality lies, here that he has been most closely followed by the philosophy of our own time. Mind, he declares, is an attribute everywhere accompanying matter, co-extensive and co-infinite with space. Our own animation is the sum or the resultant of an animation clinging to every particle that enters into the composition of our bodies. When our thoughts are affected by an external impulse, to suppose that this impulse proceeds from anything material is a delusion; it is produced by the mind belonging to the body which acts on our body; although in what sense this process is to be understood remains a mystery. Spinoza has clearly explained the doctrine of animal automatism, and shown it to be perfectly conceivable;569 but he has entirely omitted to explain how the parallel influence of one thought (or feeling) on another is to be understood; for although this too is spoken of as a causal relation, it seems to be quite different from the logical concatenation described as the infinite intellect of God; and to suppose that idea follows from idea like movement from movement would amount to a complete materialisation of mind; while our philosopher would certainly have repudiated Mr. Shadworth Hodgson’s theory, that states of consciousness are only connected through their extended substratum, as the segments of a mosaic picture are held together by the underlying surface of masonry. Nor can we admit that Spinoza entertained the theory, now so popular, according to which extension and consciousness are merely different aspects of a single reality. For this would imply that the substance which they manifest had an existence of its own apart from its attributes; whereas Spinoza makes it consist of the attributes, that is to say, identifies it with their totality. We are forced, then, to conclude that the proposition declaring thought and extension to be the same thing570 has no413 other meaning than that they are connected by the double analogy which we have endeavoured to explain. “Oh, he’s welcome to it,” Sandy cried. “I’ve turned over a new leaf!” “But—are they?” He pulled a wire out a trifle from the sheath. The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation. "Doctor, he can't die. He mustn't die," said Shorty in agony. "The regiment can't spare him. He's the best soldier in it, and he's my pardner." AND ENTERS UPON HIS PARENTAL RELATIONS TO LITTLE PETE SKIDMORE. "Holy smoke, look there," gasped Monty Scruggs, as a company of rebel cavalry came tearing over the hill in front, to the assistance of their comrades. "That's about it," answered Shorty disdainfully. "That's the way with all cavalry, dad-burn 'em. They're like a passel o' fice pups. They're all yelp and bark, and howl and showin' o' teeth. They're jest goin' to tear you to pieces. But when you pick up a stone or a club, or git ready to give 'em a good kick they're gone, the devil knows where. They're only an aggravation. You never kin do nothin' with 'em, and they kin do nothin' with you. I never kin understand why God Almighty wasted his time in makin' cavalry of any kind, Yank or rebel. All our own cavalry's good for is to steal whisky and chickens from honest soldiers of the infantry. The infantry's the only thing. It's like the big dog that comes up without any special remarks, and sets his teeth in the other dog. The thing only ends when one dog or the other is badly whipped and somethin's bin accomplished." "Mmm." Reuben started out of the half-waking state into which he had fallen. It was late in the afternoon, the sunlight had gone, and a wintry twilight crept up the wall. Maude the dairy-woman was looking in at the door. It was about a month subsequent to this, that one morning, as Turner was making the anvil ring with the ponderous strokes of his hammer, two retainers from the castle entered the shed, and delivered an order from De Boteler for his immediate attendance. Wat laid the hammer on the anvil, and, passing the back of his right hand across his forehead, to clear away the large drops that stood there, looked with a kind of smile at the men as he said, HoME泷泽萝拉四部和集下载
