Figure 2-5. Motor Phase Connector (J5)
WARNING
Motor Phase connections must match the hall sensor connection sequence. For example, MOTA
must match HALL_A, MOTB must match HALL_B, MOTC must match HALL_C. The phases must
also be in sequential order; A, then B, then C.
If the motor phases do not match the hall sensors or the connections are made out of order, the
motor will not spin smoothly and current consumption will increase.
The three phase inputs of the motor connect to MOTA/MOTB/MOTC through connector J5.
2.2 Faults, Indicators, and Jumper Settings
The DRV8300 implements Bootstrap Undervoltage, GVDD Undervoltage, and Thermal Shutdown in case of
overtemperature. See the DRV8300 Datasheet for more information on DRV8300 fault support.
The DRV8300Dxxx-EVM implements Overvoltage and Undervoltage on the PVDD and GVDD supplies as well
as Gross Over-Current protection. Status LEDs for the 3.3 V, PVDD, GVDD, and FAULT are included and shown
below.
