MLX81205/07/10/15
Features
Microcontroller: MLX16-FX RISC CPU
o 16 bit RISC CPU with 20DMIPS and Power-Saving-Modes
o Co-processor for fast multiplication and division
o Flash and EEPROM memory with EEC
o In-circuit debug and emulation
Supported bus interfaces:
o LIN-Interface with integrated LIN transceiver supporting LIN 2.x, certified LIN protocol
software provided by Melexis
o In-Module-Programming (Flash and EE) via pin LIN using a special Melexis fast protocol
o PWM-Interface
o Full duplex SPI, Master/Slave, double-buffered, speed programmable. DMA access. Flash
and EEPROM programming also possible via SPI.
TruSense Motor Control Technology
o Patented algorithms for sensor-less 3-phase sine and trapezoidal motor control
o Phase voltage integration filter for BEMF voltage sensing at lowest speeds
o Position dependent phase inductance sensing via shunt current measurements at stand still
and low to medium speeds
o Support of Star and Delta based motor configurations without the need for center star point
o Support of 3-phase switched reluctance motor control
Voltage Regulator
o Direct powered from 12V board net with low voltage detection
o Operating voltage VS = 5V to 18V
o Internal voltage regulator with possibility to use external regulator transistor
o Very low standby current, < 30µA in sleep mode, wake-up possible via LIN or local sources
Pre-Driver
o Pre-driver (~25Ω Rdson) for all 3 N-FET half bridges with programmable Inter-Lock-Delay
and slope control for optimal EMC and thermal performance during power N-FET switching
o Monitoring of Drain-Source voltages of the N-FETs
Periphery
o 4 independent 16 bit timer modules with capture and compare, and additional software
timer
o 3 programmable 12 bit PWM units with programmable frequencies
o 10 bit ADC converter (2µs conversion time) and DMA access
o On-chip temperature sensor with ±10K accuracy
o System-clock-independent fully integrated watchdog
o 32 MHz ±5% internal RC oscillator with PLL
o Optional crystal oscillator
o Load dump and brown out interrupt function
o Integrated shunt current amplifier with programmable gain
