Freescale Drives Motor Control Efficiency with Intelligent Analog IC.Integrated three-phase brushless DC solution targets small motors used in industrial, home and office electronics AUSTIN, Texas -- Freescale Semiconductor Freescale Semiconductor, Inc. is an American semiconductor manufacturer. It was created by the divestiture of the Semiconductor Products Sector of Motorola in 2004. Freescale focuses their integrated circuit products on the automotive, embedded and communications markets. (NYSE NYSE See: New York Stock Exchange :FSL FSL - Formal Semantics Language. A language for compiler writing. ["A Formal Semantics for Computer Languages and its Application in a Compiler-Compiler", J.A. Feldman, CACM 9(1) (Jan 1966)]. [Sammet 1969, p. 641]. )(NYSE:FSL.B) has introduced a three-phase brushless DC (BLDC BLDC Brushless Direct Current (motor) BLDC Boulder Labs Diversity Council ) motor driver integrated circuit (IC) designed to help drive small motors reliably with reduced board space. The MC34929 IC provides a cost-effective, small-footprint BLDC motor driver solution for a variety of consumer, portable and office equipment applications containing small motors. The single-chip MC34929 IC has built-in over-temperature, under-voltage and stalled-rotor protection circuitry, making it ideal for small-motor applications. The MC34929 operates efficiently with supply voltages from 8 V to 28 V and provides continuous motor drive current up to 1A. Designed with a built-in three-phase hall-effect sensors interface and a hall sensors voltage supply, the MC34929 motor driver IC can operate BLDC motors autonomously with a pushbutton push·but·ton n. also push button A small button that activates an electric circuit when pushed. adj. also push-but·ton Equipped with or operated by a pushbutton. or switch interface or under the control of an external microcontroller (MCU (1) (MicroController Unit) A computer on a single chip. See microcontroller. (2) (Multipoint Control Unit) A device that is used to moderate a videoconference of three or more end points (users at computers or groups of users ), such as Freescale's 8-bit MC9S08QG8CDTE MCU. Its state machine accommodates several modes of operation, including clockwise, counterclockwise, run/stop, brake, variable speed and torque current limit. "Freescale's MC34929 device provides sophisticated analog/mixed-signal integrated functions that result in a highly flexible product that is adaptable and configurable to its environment," said Arman Naghavi, vice president and general manager of Freescale's Analog, Mixed-Signal and Power Division. "It allows designers to differentiate their products with functions such as adjustable, autonomous and continuous modes." Manufactured with Freescale's proprietary SMARTMOS(TM) process, the MC34929 has built-in stall detection and protection circuitry, logic level control and various configuration and communication features for active monitoring of operation and increased reliability. Offered in a compact, low-profile 24-pin 4 mm x 4 mm x 1 mm ultra-thin QFN QFN Quad Flat No-Lead QFN Queen Fan Newsletter (rock band) QFN Quad Flat No Leads package, the MC34929 is ideal for industrial, home and office electronics applications that require a compact BLDC motor driver solution. MC34929 features * Single-supply operation (8V-28V) * Efficiently drives three-phase BLDC motors up to 1A * Autonomous BLDC control without requiring an MCU interface * Built-in hall sensors controlled-supply (VH) * Three-phase hall sensors interface * Two tachometer tachometer (tăkŏm`ətər), instrument that indicates the speed, usually in revolutions per minute, at which an engine shaft is rotating. outputs (1X and 3X hall frequency) * Adjustable maximum current limit (torque limiting) * Adjustable stalled rotor detection and protection * Short circuit detection and protection * Over-temperature detection and thermal shutdown * Under-voltage detection and shutdown * Low-profile, compact quad flat no-lead (QFN) 4x4x1mm package * Restriction of hazardous substances (RoHS) compliant Pricing and availability The MC34929 is available in production quantities at a suggested resale price of $1.42 (USD USD In currencies, this is the abbreviation for the U.S. Dollar. Notes: The currency market, also known as the Foreign Exchange market, is the largest financial market in the world, with a daily average volume of over US $1 trillion. ) in 10,000-piece quantities. The MC34929 evaluation boards are available now for a suggested resale price of $90 (USD). The KIT34929EGEVBE development tool incorporates digital I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output , making it easy to use with an MCU in a closed-loop motor control system.
