Drivers gain intelligence for LIN
systems
The MC33689 and MC33895 intelligent distributed control drivers are ideal for LIN systems that use DC motors, stepper motors and lamps.
The MC33689 and MC33895 intelligent distributed control drivers are ideal for LIN systems that use DC motors, stepper motors and lamps, such as 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 for Motorola's Transportation and Standard Product Group for the Europe/Middle East/Africa region

The LIN Consortium developed the LIN specification as a low-end multiplex solution that complements the CAN protocol and helps reduce development, production, and servicing of automotive electronics.
Motorola is the founding semiconductor manufacturer in the LIN consortium, which includes Audi, BMW, Daimler Chrysler, Volvo Car Corporation, Volkswagen and Volcano Communications Technologies (VCT).
The MC33689 and MC33895 integrate a 5V voltage regulator with reset function and protection, three operating modes (normal, stop, sleep), and integrated LIN transceiver with optimised EMC performance (active wave shape).
The MC33689 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 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 process, the MC33689 and MC33895, complement Motorola's line of microcontrollers and analogue ICs for various LIN slave actuator control applications.
The devices combine high-density/high-speed logic with precision analogue 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.
The MC33689 and MC33895 are available now in samples quantities with production quantities expected to be available in the first half of 2003.
Pricing starts at $1.46 (MC33689D, US suggested list price) and $2.99 (MC33895D, US suggested list price) for 10,000-piece quantities.
