a standard PWM generators, high-­
resolution PWM generation with Micro
Edge Positioning (MEP) technology
enables higher performing systems.
HRPWMs support high timing resolution
for duty cycle, period and phase offset
settings during PWM generation, providing unparalleled performance for the
range of PWM generation and synchronization techniques required in power
electronics applications.
See page 370 of the TMS320F2806x Technical Reference Manual to learn more.
Ultra-Configurable PWM
Waveforms
A multitude of configuration options
enables generation of advanced PWM
waveforms. PWM duty cycle can be
configured according to zero, period,
CMPA and CMPB timer events.
Independent rising and falling edge deadband prevents energy losses. Phase relationships between PWM waveforms are
supported. From buck converter control
to LLC resonant converter control, C2000
PWMs have what it takes.
See page 241 of the
TMS320F2806x Technical
Reference Manual to learn more.

Feature Guide
Robust System Protection
and Control
Integrated analog comparators are tied
to ADC inputs and provide overcurrent or
overvoltage system protection, asynchronously shutting down (i.e., fault trip) PWM
outputs in as little as 50 ns. Furthermore,
with included ramp generation logic,
advanced power stage control—like peak
current mode control—can be implemented for power supply applications.
See page 521 of the TMS320F2806x Technical Reference Manual to learn more.
Ready-to-Use Analog
Comparators
Analog comparators on C2000 MCUs
come ready-to-use. The analog comparators are tied internally to the ADC input
pins, which means they require no external routing or additional pin utilization.
This saves board routing space, frees up
MCU pins for other functions, reduces
latency and makes it easy for designers
to implement system protection.
See pages 84 and 95 of the
TMS320F2806x Data Sheet to
learn more.
Tripping When You Want It
Analog comparators on C2000 MCUs
also include blanking window and filtering features, allowing removal of noise
and unwanted PWM trip triggering.

Feature Guide
Peak Current-Mode Control
Capable
C2000 MCUs bring the benefits of digital
control to even the more complex control
methodologies like peak current-mode
control. Designers can build high-­
performance digital power supplies
controlled by peak current-mode control
with slope compensation support.
See page 328 of the
TMS320F2806x Technical
Reference Manual to learn more.
High-Resolution Signal
Detection
With high-resolution captures (HRCAP),
you can detect input signal edges at
a clock resolution of 300 ps versus
16,667 ps for a normal capture interface. This introduces less error into your
system when you need to detect highfrequency digital signals from external
sensors and other interfaces.
With the HRCAP, systems can achieve
greater accuracy of measurements like
speed and distance, or realize greater
sensitivity for short-pulse applications
like capacitive touch.
See page 402 of the TMS320F2806x Technical Reference Manual to learn more.
Encoder Motor Feedback
With the Quadrature Encoder Pulse
Module (QEP), you can interface with
linear or rotary incremental encoders, providing position, direction and
speed measurements in motion-control
systems. Benefits include flexible interfacing to support a variety of encoders,
support for low-speed measurements,
and motor stall detection.
