WARNING
To minimize the risk of potential shock hazard and personal injury, remove all power connections and
interfaces to the DRV8300Dxxx-EVM when not in use.
The DRV8300Dxxx-EVM is designed for an input supply from 6 V
DC
to 100 V
DC
and up to 25-A continuous drive
current (software limited). The input connects to J4 with the noted polarity. PVDD_TP connects to the same node
but must not be used for high current input. PVDD input is fused with a 30 A fuse and the input connector is
rated for 32 A.
Figure 2-4. Hall Sensor Input and Power Connections (J7)
Hall sensors are connected to J7 including hall power and GND. The 3.3 V
DC
supply to the Hall sensors is
supplied from the 3.3 V LDO on the EVM. External hall power can be input through the HALL_EXT test point if a
different supply or voltage level is desired. To use the included 3.3 V LDO to power the halls, connect J3 on the
right side to pins 1:2 as shown. To use HALL_EXT, connect J3 on the left side to pins 2:3. To insert or remove
wires/terminals on J7, use a flat blade screwdriver to push down the respective tab on top of the J7 connector.
