Getting Familiar with the Kit
Kit Contents
The DRV830x EVM is usually available packaged as a full solution kit:
•
MCU controlCARD
•
DRV830x EVM board with slot for the controlCARD
•
USB Cable
•
USB/DVD with CCStudio IDE, GUI, documentation, and link to project software
distribution
•
Some versions ship with a tabletop 24V 2.5A power supply and 24V Motor with built-in
Hall Sensors and Encoder
The DRV830x EVM board can accept many of the TI MCU controlCARDs, but we recommend
using the versions that ship with the kits that include the JTAG emulator, USB to serial, and
isolation on the controlCARD. It is recommended to always check for any updates to the GUI
executable and MCU program.
Board Features
:
The board has the following features
•
Three-Phase Power Stage, DRV830x capable of driving 3-phase brushless DC motors
and Permanent Magnet Synchronous Motors.
60V DC max input voltage
o
60A peak output current per phase
o
Up to 200khz driver switching frequency
o
Integrated 1A buck converter to provide logic and analog power
o
Dual integrated current sense amplifiers
o
•
Isolated CAN and SPI communication (will only work if MCU supports and SW is
enabled)
•
JTAG connector for external emulators
•
Quadrature Encoder Interface and Hall Sensor Interface available for speed and position
measurement (only if MCU supports and SW is enabled)
•
High precision low-side current sensing using integrated current sense amplifiers in the
DRV830x (2-ch) or optional external 3-ch (Starting with DRV8301 RevD)
•
Over current protection on the inverter stage by DRV830x
•
Hardware Developer's Package that includes schematics and bill of materials
•
Closed-loop digital control with feedback using the MCU's on-chip PWM and ADC
peripherals
Warning: about low switching frequencies on the DRV830x
When the DRV830x runs at a low switching frequency (e.g. less than 20 kHz with 100 nF
bootstrap capacitor), the bootstrap capacitor voltage might not be able to maintain a proper
