Functional description
The MTC can be split into five main parts as shown in the simplified block diagram in
Figure
PWM output
reference signals.
Duty cycle
Input detection block with a comparator, an input multiplexer and an incremental
encoder interface, which may work as:
–
–
The delay manager with an 8/16-bit timer and an 8x8 bit multiplier, which may work as:
–
–
The PWM manager, including a measurement window generator, a mode selector and
a current comparator
The channel manager with the PWM multiplexer, polarity programming, deadtime
insertion and high frequency chopping capability and emergency HiZ configuration
input
The three-phase PWM generator with 12-bit free-running counter and repetition
counter
78. Each of these parts may be configured for different purposes:
a BEMF zero-crossing detector
a speed sensor interface
an 8-bit delay manager
a speed measurement unit
