INTRODUCTION
The DRV10866EVM is a complete solution for evaluating the DRV10866 5-V, three-phase sensorless
BLDC motor driver. It includes a TLC555 timer configured to supply a PWM to the DRV10866, a
potentiometer to adjust the speed of the motor by varying the duty cycle of the PWM, a jumper on the FG
pin to allow the use of an external pull up resistor, and a jumper on the FGS pin to set ½ or normal
frequency output on the FG pin. Power can be provided with the included micro-USB cable for 5 V or
externally provided, up to 5.5 V, through the power header. The PWN, FG, and GND signals are all
brought out to surface mounted test points.
The DRV10866EVM is configured so that connections to only the motor and power supply are required.
2.1
Power Connectors
The DRV10866EVM uses a combination of headers and a USB input jack (on bottom side) for the
application/monitoring of power. For the EVM, only a single power supply rail is necessary. Minimum
recommended VIN for the EVM is 2 V and maximum is 5.5 V. Please see the datasheet for the DRV10866
for complete voltage range information of the driver itself. When power is supplied to the board a green
LED (D3) in the bottom right corner should enable.
The overcurrent threshold setup pin sets the current limit for the device and is connected to a 3.8-kΩ
resistor (R6) on the DRV10866EVM. This sets the current limit at 820 mA for the DRV10866. This resistor
can be replaced and a new current limit set using the equation seen below. Please see the datasheet for
the DRV10866 for more information on the overcurrent threshold setup pin.
ILIMIT (mA) = 3120/RCS (kΩ)
(1)
VCC for the DRV10866 is directly taken off the micro USB jack supply or J4 power supply header. The J4
header is located on the top side of the EVM near the bottom right of the board as shown in Figure 3. The
micro USB jack is located on the bottom side of the board as shown in Figure 4. The micro USB jack is
only to supply power for the EVM and does not provide any additional functionality. Please choose only
one method for providing power to the EVM.
Figure 3. Top View (J4 Power Supply Header)
Figure 4. Bottom View (Micro USB Jack)
NOTE: It is only necessary to provide one source of power for the EVM. DO NOT connect to both
the micro USB jack and the J4 power supply header.
2.2
Test Points
Test points are provided and labeled according to the inputs/outputs of the DRV10866 motor driver. 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 your own PWM signal to the motor driver, remove the 0-Ω
resistor (R6) and connect your own 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 (R1) located on the EVM.

The FG signal’s frequency represents the motor speed and phase information.
RPM = (FG x 60)/pole pairs
(2)
Refer to the data sheet of the DRV10866 for more information regarding the FG pin.
2.3
Jumpers
There are two jumpers (J1 and J2) on the EVM that are normally installed.
One jumper connects the FG pin of the DRV10866 to a pull up resistor and the other jumper determines
whether FG is ½ or normal frequency output by connecting FGS to either VCC or GND.
For normal operation right out of the box both jumpers should be installed.
2.3.1
FGS Frequency Generator Select (J1) Jumper
J1 can be found in the image below, Figure 5. Installing the jumper connects the FGS pin on the
DRV10866 to GND. When the FGS pin is tied to GND, the FG output of the DRV10866 is set for normal
frequency output. With the jumper out, the FGS pin pulls up to VCC. When the FGS pin is tied to VCC, the
FG output of the DRV10866 is set for ½ of the original FG frequency. FGS is latched upon power to the
EVM so power must be cycled in order for the FG output to change.

FG Pullup (J2) Jumper
JP2 can be found in Figure 6. Installing the jumper connects the FG pin of the DRV10866 to an on board
pull up resistor.
Figure 6. J2 Location
To make an external connection to FG, the jumper can be removed and pin 1 of the header provides a
direct connection to the FG pin of the DRV10866. Pin 1 of J2 is highlighted in the image below, Figure 7.
Note that if the jumper is removed, an external pull up resistor is needed for connection of FG to an
external system. For more information regarding the FG pin please refer to the datasheet of the
DRV10866.

Speed Adjust Potentiometer (R1)
The speed adjust potentiometer (Spd_Adj) can be found in Figure 8. The potentiometer adjusts the duty
cycle of the PWM signal which will in turn adjust the speed of the motor. In order to lower the duty cycle
and in turn lower the speed, turn the potentiometer counter-clockwise. In order to increase the duty cycle
and in turn increase the speed, turn the potentiometer clockwise.
Figure 8. Speed Adjust Potentiometer
The onboard PWM signal for the DRV10866 is generated by a circuit based upon the Texas Instruments
TLC555 low power timer. It is capable of an approximately 25-kHz output that can be adjusted from 5% to
95% duty cycle. This square output signal will switch from 0 V to VCC.
In order to provide an external PWM signal to the DRV10866, first remove the 0-Ω resistor (R6). Next,
connect the external PWM signal to the “PWM” surface mounted test point. For more information on the
PWM input required by the DRV10866 please refer to the datasheet.

EVM Use Restrictions and Warnings:
4.1 EVMS ARE NOT FOR USE IN FUNCTIONAL SAFETY AND/OR SAFETY CRITICAL EVALUATIONS, INCLUDING BUT NOT
LIMITED TO EVALUATIONS OF LIFE SUPPORT APPLICATIONS.
4.2 User must read and apply the user guide and other available documentation provided by TI regarding the EVM prior to handling
or using the EVM, including without limitation any warning or restriction notices. The notices contain important safety information
related to, for example, temperatures and voltages.
4.3 Safety-Related Warnings and Restrictions:
4.3.1
User shall operate the EVM within TI’s recommended specifications and environmental considerations stated in the user
guide, other available documentation provided by TI, and any other applicable requirements and employ reasonable and
customary safeguards. Exceeding the specified performance ratings and specifications (including but not limited to input
and output voltage, current, power, and environmental ranges) for the EVM may cause personal injury or death, or
property damage. If there are questions concerning performance ratings and specifications, User should contact a TI
field representative prior to connecting interface electronics including input power and intended loads. Any loads applied
outside of the specified output range may also result in unintended and/or inaccurate operation and/or possible
permanent damage to the EVM and/or interface electronics. Please consult the EVM user guide prior to connecting any
load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative.
During normal operation, even with the inputs and outputs kept within the specified allowable ranges, some circuit
components may have elevated case temperatures. These components include but are not limited to linear regulators,
switching transistors, pass transistors, current sense resistors, and heat sinks, which can be identified using the
information in the associated documentation. When working with the EVM, please be aware that the EVM may become
very warm.
4.3.2
EVMs are intended solely for use by technically qualified, professional electronics experts who are familiar with the
dangers and application risks associated with handling electrical mechanical components, systems, and subsystems.
User assumes all responsibility and liability for proper and safe handling and use of the EVM by User or its employees,
affiliates, contractors or designees. User assumes all responsibility and liability to ensure that any interfaces (electronic
and/or mechanical) between the EVM and any human body are designed with suitable isolation and means to safely
limit accessible leakage currents to minimize the risk of electrical shock hazard. User assumes all responsibility and
liability for any improper or unsafe handling or use of the EVM by User or its employees, affiliates, contractors or
designees.
4.4 User assumes all responsibility and liability to determine whether the EVM is subject to any applicable international, federal,
state, or local laws and regulations related to User’s handling and use of the EVM and, if applicable, User assumes all
responsibility and liability for compliance in all respects with such laws and regulations. User assumes all responsibility and
liability for proper disposal and recycling of the EVM consistent with all applicable international, federal, state, and local
requirements.
