DRV10963EVM
Introduction
VCC for the DRV10963 is available through two connections. A USB micro connector can provide power
to the EVM by connecting J1 on the bottom of the EVM. The H1 header can also be used to power the
EVM. The H1 header is located on the top side of the EVM near the middle of the board, as shown in
to the EVM by connecting J1 on the bottom of the EVM. The H1 header can also be used to power the
EVM. The H1 header is located on the top side of the EVM near the middle of the board, as shown in

Test Points
Test points are provided and labeled according to the inputs and outputs of the DRV10963 motor driver.
The signals brought out to test points are labeled FG, PWM, and GND.
The signals brought out to test points are labeled FG, PWM, and GND.
The signal PWM is generated by circuitry on the EVM. In order to provide an external PWM signal to the
motor driver, remove the 0.0-
motor driver, remove the 0.0-
Ω
resistor (R4) and connect the external PWM signal to the PWM test point.
The PWM signal generated by the circuitry on the EVM is approximately 25 kHz and can be adjusted from
5% to 95% duty cycle by the potentiometer (R6) located on the EVM.
5% to 95% duty cycle by the potentiometer (R6) located on the EVM.
The FG signal’s frequency represents the motor speed and phase information.
RPM = (FG × 60) / pole pairs if FGS = 0 or
RPM = (FG × 30) / pole pairs if FGS = 1
Please refer to the DRV10963 datasheet (
) for more information regarding the FG pin.
