Features

Microcontroller: MLX16-FX RISC CPU

16 bit RISC CPU with 20DMIPS and Power-Saving-Modes

Co-processor for fast multiplication and division

Flash and EEPROM memory with EEC

In-circuit debug and emulation

Supported bus interfaces:

LIN-Interface with integrated LIN transceiver supporting LIN 2.x, certified LIN protocol

software provided by Melexis

In-Module-Programming (Flash and EE) via pin LIN using a special Melexis fast protocol

PWM-Interface

Full duplex SPI, Master/Slave, double-buffered, speed programmable. DMA access. Flash

and EEPROM programming also possible via SPI.

TruSense Motor Control Technology

Patented algorithms for sensor-less 3-phase sine and trapezoidal motor control

Phase voltage integration filter for BEMF voltage sensing at lowest speeds

Position dependent phase inductance sensing via shunt current measurements at stand still

and low to medium speeds

Support of Star and Delta based motor configurations without the need for center star point

Support of 3-phase switched reluctance motor control

Voltage Regulator

Direct powered from 12V board net with low voltage detection

Operating voltage V_S= 5V to 18V

Internal voltage regulator with possibility to use external regulator transistor

Very low standby current, < 30µA in sleep mode, wake-up possible via LIN or local sources

Pre-Driver

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

Monitoring of Drain-Source voltages of the N-FETs

Periphery

4 independent 16 bit timer modules with capture and compare, and additional software

timer

3 programmable 12 bit PWM units with programmable frequencies

10 bit ADC converter (2µs conversion time) and DMA access

On-chip temperature sensor with ±10K accuracy

System-clock-independent fully integrated watchdog

32 MHz ±5% internal RC oscillator with PLL

Optional crystal oscillator

Load dump and brown out interrupt function

Integrated shunt current amplifier with programmable gain
