Motorola Launches LIN Power ICs for Distributed Motion Control

MUNICH, Germany, Sept. 19 /PRNewswire-FirstCall/ -- Designers of LIN-based systems now have additional options to help simplify system design, drastically reduce board space, and increase system reliability by using power integrated circuits (ICs) from Motorola, Inc.'s (NYSE: MOT) Semiconductor Products Sector.

The MC33689 and MC33895 Intelligent Distributed Control Drivers are ideal for local interconnect network (LIN) systems that use DC motors, stepper motors and lamps. Key applications include door locks and mirrors in automobiles, copiers, printers, robotics, computer numerical control machining systems, and electrical actuators in appliances.

"Motorola products enable car manufacturers to more easily support multiple tiers of automobiles with common electronic module designs, sometimes referred to as plug and play," said Juergen Weyer, vice president and general manager of Motorola's Transportation & Standard Product Group for the Europe/Middle East/Africa region. "These advanced power ICs help to minimize the hardware design effort, allowing our customers to focus on the software and drastically improve their time to market as well as system reliability and cost. In addition, the advanced LIN transceiver integrated onto the MC33689 and MC33895 products is setting the market standard in its domain."

LIN is a low-cost, class A serial communication system for distributed electronic systems in vehicles. The LIN Consortium developed the LIN specification as a low-end multiplex solution that complements the Controller Area Network (CAN) protocol, while helping to reduce development, production, and servicing of automotive electronics. Motorola is the founding semiconductor manufacturer in the LIN consortium, which includes Audi AG, BMW AG, Daimler Chrysler AG, Volvo Car Corporation AB, Volkswagen AG and Volcano Communications Technologies AB (VCT).

Features

The MC33689 and MC33895 devices integrate a 5V voltage regulator with reset function and protection, three operating modes (normal, stop, sleep), and integrated LIN transceiver with optimized electromagnetic compatibility (EMC) performance (active wave shape).

The MC33689 IC is intended for LIN slave nodes driving a relay. Therefore, it includes two 150mA high side switches, one 50mA high side switch for a Hall sensor or external switch pull-up bias, two 40V wake up inputs and a current sense amplifier. The device is assembled in a SOW54 exposed pad fine pitch package.

The MC33895 IC is intended for LIN slave node multipurpose drivers. Therefore, it includes four half bridges with diagnostics and programmable current control and recopy, one high side switch for a 10W lamp, back electromagnetic field (BEMF) signal generation for stall detection, 40V wake up inputs, and three 2-pin Hall sensor inputs. The device is assembled in a SOW32 fine pitch package.

Manufactured with Motorola's SMARTMOS(TM) process, the MC33689 and MC33895 devices complement Motorola's line of microcontrollers (MCUs) and analog ICs for various LIN slave actuator control applications. The devices combine high-density/high-speed logic with precision analog and high-voltage/high- current power circuitry. And they include built-in current limiting, built-in thermal shutdown, built-in under-voltage shutdown, versatile output control and load status reporting. In addition, both ICs include robust built-in protection features and logic level control and communication to help simplify LIN system design efforts, lower system costs and increase system reliability.

Price and Availability

The MC33689 and MC33895 devices are available now in sample quantities, with production quantities expected to be available in the first half of 2003. Suggested list unit pricing starts at $1.46 (USD) (MC33689D) and $2.99 (MC33895D) for 10,000-piece quantities.

Motorola also offers a full complement of LIN master MCUs based on the msCAN module with the 68HC(9)08GZ and 68HC(9)08AZ family of parts, along with the 16-bit HC9S12 family for high-performance LIN master node applications. In addition, Motorola is introducing the 68HC908EY "slave" controller for a range of in-vehicle communications and networking needs in a variety of body electronics and powertrain applications.

Motorola's system solutions include chips, software libraries and example application code, development tools, comprehensive technical documentation, and engineering support that help make it easier for customers to design, develop, debug and bring products to market faster. Software and development systems are available from Metrowerks. When these offerings are combined with development starter kits, simulation expertise and an unrivaled network of applications support, Motorola provides customers with system solutions to develop and implement low-cost LIN bus applications.
