MLX81150 from Melexis, a single die device with on-chip high voltage component

Melexis has made available MLX81150, a device integrating automotive grade high voltage components, flash memory, digital and mixed signal blocks on a single die. The MLX81150 is suitable for different smart actuator applications such as window lifter, roof control, engine flaps, seatbelt retractors and others. Using 0.18micron technology Melexis has successfully integrated devices operating at low voltage and high voltage on a single silicon die.

The MLX81150 integrates a physical layer LIN transceiver, a voltage regulator and a 16-bit microcontroller with 32kB flash memory including the peripheral functions like high voltage IOs, timer, ADC with differential amplifier for current monitoring, PWM-unit and EEPROM. The high voltage mixed signal integration of the 0.18µm process enables the inclusion of a relay driver with free wheel function to support relay based DC applications like window lifters.

The MLX81150 has the possibility to connect directly to external power MOS transistors in half or full bridge configuration without an additional pre-driver IC to drive DC-motors of seatbelt retractors. The high temperature capability offers the possibility to realize smart engine applications like EGR Flaps or throttle valves.

As a microcontroller core it uses the 4-bit/16-bit dual task implementation, where the 4-bit task takes care of communication and the 16-bit task is completely free for the motor control algorithm. A LIN Software driver meets the communication tasks of all LIN protocols (LIN1.3, LIN2.x and J2602) available and functions like a complete high level development environment.
