Requirements
The BOOSTXL-DRV8305EVM is not a standalone motor control kit and requires a compatible XL
LaunchPad to provide the appropriate motor control signals. The BOOSTXL-DRV8305EVM has been
specifically designed for the LAUNCHXL-F28027F InstaSPIN-FOC LaunchPad. In addition to the
BoosterPack and a compatible XL LaunchPad, a 3-phase motor and sufficient power supply are required.
3.2
Configuring the LaunchPad
The BOOSTXL-DRV8305EVM BoosterPack supplies 3.3 V to the LaunchPad through the onboard
LMR16006 0.6-A, step-down buck regulator. It is recommended to remove the jumpers on the LaunchPad
that connect the emulation and controller power supplies. The LaunchPad communication lines should
also be configured to ensure proper operation from the host PC.
Example: LAUNCHXL-F28027F
For the LAUNCHXL-F28027F LaunchPad, remove the JP1 (3.3 V), JP2 (GND), and JP3 (5 V) jumpers to
isolate the two power supply domains (MCU and Emulator).
The S1 switch should be set to the ON-ON-ON position to allow for a JTAG debug connection. The S4
switch should be moved to the OFF position to allow for the nFAULT pin from the DRV8305 to report
correctly.
