JTAG connector for external emulators (not used with Stellaris microcontrollers)
Quadrature Encoder Interface (QEI) available for speed and position measurement
Hall-Sensor Interface for sensored three-phase motor control
High precision, low-side current sensing using the Stellaris microcontroller’s
high-performance ADC, Texas Instruments’ OPA365A high-speed op-amps, and Texas
Instruments’ REF3025 high precision voltage reference chip
Three PWM DACs generated by low-pass filtering the PWM signals to observe the
system variables on an oscilloscope to enable easy debug of control algorithms
Over-current protection on the inverter stage, DRV8312
The software available with the kit is pre-optimized for the motors that are available with the
kit. The software is open source, and therefore, can be easily modified to tune and run a
different motor. The following motor is available with the kit:
Nema Size 17 BLDC Motor
(11A peak current , 4000RPM)
WARNING: Low-Switching Frequencies on the DRV8312
When the DRV8312 runs at a low switching frequency (for example, less than
20 kHz with 47 nF bootstrap capacitor), the bootstrap capacitor voltage might
not be able to maintain a proper voltage level for the high-side gate driver. A
bootstrap capacitor under voltage protection circuit (BST_UVP) will start
under this circumstance to prevent the potential failure of the high-side
MOSFET.
In this circumstance, both the FAULT and OTW pins should pull low and the
device should self-protect itself. The motor’s inductance and the inverter’s
bootstrap capacitance will allow the DRV8312 to run efficiently until
approximately 10 kHz (with margin). Setting the PWM switching frequency
below 10 kHz may cause issues on the inverter output and is not
recommended. See the DRV8312 data sheet for more information.
Hardware Overview
Figure 3 shows a typical motor drive system running from either a laboratory power supply
or the 24 V supply delivered with the kit. The DRV8312-C2-KIT’s motor control board has
all the power and control blocks that constitute a typical motor drive system for a step motor
or two brushed DC motors (Figure 5).

Macro Blocks
The motor control board is divided into functional groups that enable a complete motor drive
system. These functional groups are called macro blocks. This list describes the macro blocks
that are present on the board and their functions::
•
•
•
•
•
•
ISO controlCARD socket – Socket for a Stellaris or C2000 MCU-based controlCARD
DC Bus Connection
• J9 power entry jack - Connect the supplied +24 V power supply here
• “PVDD/GND” Terminals – Connect an external lab supply here making sure to
observe correct polarity
Aux-12 V Control Power Entry – Connectors to optionally provide an external 12 V
supply for logic and gate drive power. The 12 V supply can also be regulated on-board
from the DC bus depending on the setting of JP1. Set to the “VR1” position to use the
on-board regulator. Set to position “+12 V” to use the external regulator.
DRV8312 – This module includes the DRV8312 Three-Phase PWM Motor Driver and all
of the necessary external passive components.
Current Sense – Low-side shunt current sensing on each half-bridge.
Reset Switch – Individual reset for each half-bridge. Reset can be forced manually from
the three-position switch or through a GPIO from the MCU. Setting switch in the down
position, “RESET” disables the half-bridge outputs. Setting the switch in the middle
position will allow control through a GPIO on the MCU. Setting the switch in the up
position, “NORMAL OP” disables control from the MCU and enables the half-bridge
outputs.

Mode Jumper “M1” – DRV8312 mode can be set to select between cycle-by-cycle
current limit or latched over-current.
Quadrature Encoder Connections – Connections are available for an optional shaft
encoder to interface to the MCU’s QEP peripheral.
Hall Effect Sensor Connections – Connections are available for optional Hall Effect
Sensors.
Figure 4 shows the position of the macro blocks on the board. All the PWMs and ADC
signals which are the actuation and sense signals have designated test points on the board,
which makes it easy for an application developer to try out new algorithms and strategies.

Board Power
The board is separated into two power domains*: (1)the low voltage Controller Power
domain powers the controller and the logic circuit present on the board, and (2) the medium
voltage power delivery line that is used to carry the medium voltage and current such as the
DC power for the Inverter (also referred to as DC Bus).
1) Controller Power comprised of the 12 V, 5 V, and 3.3 V that the board uses to power the
controller and the logic and sensing circuit present on the board. This power can be sourced
from two places (Jumper JP1 selects between the two):
•
•
+12V DC control power entry: Connect an external bench supply with 1A current limit
here
On board regulator, VR1: +12V is regulated from DC bus power via an on-board buck
regulator
2) DC Bus Power is the medium voltage line – up to 52.5V - that provides the voltage to the
inverter stage to generate three phases to control the motor(s). Connect supplied 24 V
regulator to J9.
For step-by-step instructions on configuring the DRV8312 baseboard for use with a Stellaris
controlCARD, see the DK-LM3S-DRV8312 Read Me First document.

TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
