Pinout
The BOOSTXL-DRV8301 brings out a combination of power, control, and feedback signals to the XL
LaunchPad headers.
Figure 4. Booster Pack Pinout
•
Onboard step-down buck converter of the DRV8301 device to provide 3.3-V power to the LaunchPad
•
Fault reporting through the nFAULT and nOCTW signals
•
SPI interface to set device configuration, operating parameters, and read out diagnostic information
•
Independent control through three or six PWM inputs
•
Voltage sense for the DC bus and each phase output (scaled for 6-V to 24-V operation)
•
Low-side current shunt sensing on each phase (scaled for 0-A to 14-A peak operation)

Requirements
The Motor Drive Booster Pack is not a standalone evaluation kit. It requires a compatible XL LaunchPad
to provide the appropriate control signals. The Motor Drive Booster Pack and compatible XL LaunchPad
also require a 3-phase motor and sufficient power supply.
