The DRV10974 EVM requires a V
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
2. Use the default ADV, RMP, and CS resistor values (or set them up in
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
the potentiometer (R5) to control the speed.
•
For using a PWM signal to control the speed: match the jumpers as shown in
the PWM signal to the PWMIN test point.
4. Power up the board and turn the switch S1 to the On (Down) position.
