The DRV10974 EVM requires a VCC power supply source, which has a recommended operating range
from 4.4 V to 18 V. Use the following sequence to power up the EVM:
Figure 2. DRV10974 EVM With Various Connections and User Interface
1. Connect the power supply ground to pin 2 (GND) and a voltage between 4.4 V and 18 V to pin 1 of
connector P1 (Power In). Set the current limit on the power supply to 1.5 A and make sure switch S1 is
in the Off (Up) position as shown in Figure 2.
2. Use the default ADV, RMP, and CS resistor values (or set them up in Section 7).
3. Determine whether to use an analog voltage or PWM to control the speed of the motor.
• For using an analog voltage to control the speed: match the jumpers as shown in Figure 3 and use
the potentiometer (R5) to control the speed.
• For using a PWM signal to control the speed: match the jumpers as shown in Figure 4 and connect
the PWM signal to the PWMIN test point.
4. Power up the board and turn the switch S1 to the On (Down) position.

•Select (J3) is used to configure motor speed-control resources for the PWM pin. Set the PWM jumper
to PWMIN for sending a PWM signal to the PWM pin to control motor speed. See Figure 4 for more
details. Set the PWM jumper to Analog with J2 connected for using potentiometer (R5) to control motor
speed. See Figure 3 for more details.
•J7 and J11 Connections are placeholders for an I2C interface, so they can be ignored.
Figure 12. Potentiometer Power Header (J2)
•Potentiometer Power (J2) provides voltage from the V1P8 pin of the DRV10974 device to power the
potentiometer. This header must be jumpered to use the potentiometer.
6.2 Switch
The S1 switch allows the applied power supply voltage to reach the rest of the board. A fuse is used to
protect the device from overcurrent. Turn the switch to the On position to power the EVM.

7 CS, RMP, and ADV Resistor Selection
Note that the three pins, CS, RMP, and ADV, are used to configure settings for the DRV10974 device.
The receptacles (J10, J9, and J8) on the CS, RMP, and ADV pins are used for installing axial-lead,
through-hole resistors to quickly configure settings on the DRV10974EVM. Note that R6, R7, and R8 are
0402, 0-Ωsurface-mount resistors in series with the receptacles. They give the user flexibility to achieve
the desired resistor values if necessary.
In addition, the 0603 surface mount resistors (R4, R3, and R2) can also be replaced or removed to
configure the settings. Because these resistors are populated by default, it is highly recommended to
remove these resistors or to calculate the parallel resistance if the receptacles are used. This is shown in
Figure 13. See the DRV10974 Tuning Guide for more information.
Furthermore, ensure all resistors have 1% tolerance for CS, RMP, and ADV pins.
7.1 CS Resistor Table
The CS resistor controls the current limit setting on the DRV10974 device. More information can be found
in DRV10974 12-V, Three-Phase, Sensorless BLDC Motor Driver. The default resistor on the
DRV10974EVM is 115 kΩ, which sets the current limit to 1.4A.

7.2 RMP Resistor Table
The RMP resistor controls the open-loop start-up acceleration, closed-loop acceleration, and closed-loop
deceleration. More information can be found in DRV10974 12-V, Three-Phase, Sensorless BLDC Motor
Driver. The default resistor on the DRV10974EVM is 7.32 kΩ, which sets the second-order acceleration
coefficient, the first-order acceleration coefficient, the closed-loop acceleration, and the closed-loop
deceleration to 0.22 Hz/s2, 4.6 Hz/s, 2.7 s, and 44 s, respectively. This is the slowest ramp rate.
