Melexis is one of the leading suppliers of Automotive Intelligent Actuator ASICs.
These ASICS combine in any shape and flavor a combination of the below key IP blocks:
• INTELLIGENCE / PROGRAMMABILITY
o ROM mask or up to 32kByte of Flash for production
o Single or Dual task 4bit or 16bit RISC microcontrollers
• MOTOR CONTROL
o Integrated motor drivers up to 500mA (DC /BLDC /Stepper)
o Relay /FET drivers for DC motors
o FET predrivers for sensored/sensorless BDLC motors, including full motor control: Block - Trapez. - Sine - Space Vector - ...
• SENSING
o Integrated Hall Effect Sensors: Switch/Latch - Linear - 2d/3D Triaxis Vertical Hall
o Pulse count or Ripple count for sensorless DC motor control.
o BEMF sensing for sensorless BLDC motor control
• COMMUNICATION
o SPI, Analog, PWM, SENT, LIN, ...
• HIGH VOLTAGE interface
o LIN physical layer
o Integrated supply regulation
o Analog and digital IO (switches, battery monitoring, ...)
o Loaddump, schaffner pulses, jumpstart, … compliant
As a result of the combination of our automotive expertise, applications know how and wide range of IP blocks, Melexis enables customers to realize unique solutions that make them stand out from their competition. ASIC development time can be minimized through the extensive reuse of IP, and the availability of Flash for production.
Key to our innovative strategy is our close ties to our wafer foundry partners. Depending on the application requirements the most suitable technology is chosen to realize the integration level that offers the best system level price/performance ratio.
With its LIN physical layer, that is approved by the major car manufacturers, Melexis is your ideal partner for intelligent LIN slaves in this fast emerging market.
