Cost-Optimized LIN Controller ICs Strengthen Melexis’ Automotive Networking Portfolio

Tessenderlo, Belgium --- Melexis expands its extensive array of ICs and board level products designed for use in LIN implementations, with the unveiling of the MLX81107/MLX81109 offering. Combining high degrees of built-in functionality and low unit costs, these freely-programmable, monolithic devices are able to address growing demands within the automobile industry for sophisticated LIN-based switches, actuators, drivers, sensor interfaces and LED lighting systems.

The MLX81107 and MLX81109 both incorporate a physical layer LIN transceiver, LIN controller, voltage regulator, 16-bit RISC-based microcontroller, 32kBytes of Flash memory and 20-channel analog-to-digital converter (ADC), as well as possessing 16-bit pulse width modulation (PWM) capabilities. The LIN protocol handler is compliant with LIN 2.0, LIN 2.1 and LIN 2.2, as well as SAE J2602. The ICs have 4 high voltage capable (12V direct) IOs, plus 8 low voltage capable (5V) IOs. Through these interfaces, communication with the vehicle’s LIN infrastructure is facilitated. Every IO can be programmed to control the application components using the built-in Flash memory resource.

The high level of integration exhibited in the MLX81107/9 devices dramatically reduces both the bill of materials (BoM) costs and board space utilization. The combination of the LIN controller and approved LIN driver together with directly controlled high/low voltage capable IOs means that LIN can be rapidly implemented into a wide variety of different applications. As these ICs are supplied in 5mm x 5mm QFN packages, thermal performance is maximized and board real estate is conserved. To ensure their reliability in challenging automotive environments, an operational temperature range of -40°C to 125°C is supported, with over-temperature shutdown and load dump (40V) protection mechanism included.
