DRV8313 EVM Hardware Macro Blocks
The motor control board is separated into functional groups that enable a complete motor drive system;
these are referred to as macro blocks. Following is a list of the macro blocks present on the board and
their functions:

their functions:
•
DC bus connection at terminal block J2
•
3-phase motor connection at terminal block J3
•
DRV8313 – This module includes the DRV8313 three phase PWM motor driver as well as all of the
necessary external passive components.

•
On board MSP430G2553 value line micro-controller with 8k flash
•
USB interface- Micro-USB interface connector is used for serial UART communication with FTDI driver
chip to run the EVM using GUI through external PC/Laptop

•
Current sense – Low-side shunt current sensing on dc-link current measurement
•
On board 5V
CC
control power supply for hall-effect sensors and 3.3-V supply for MCU
•
On board potentiometer for speed control to run BLDC motor in stand-alone mode without using GUI
•
4-pin JTAG interface connector for SPI-BY-WIRE Programming
•
16-pin connector – This provides interface to all control signals of DRV8313 and it can be used to drive
DRV8313 from an external micro-controller

•
Hall effect sensor connections – Connections are available for optional Hall effect at J7. The included
GUI only supports sensor-less commutation. Hall connections are provided for use when developing a
sensored motor project.

illustrates the position of these macro blocks on the board. The use of a macro block approach
for different power stages enables easy debugging and testing of one stage at a time. All the PWM 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.
