I
Overcurrent threshold setup pin. The constant current of the internal constant current source
flows through the resistor connected to this pin. The other side of the resistor is connected to
ground. The voltage across the resistor compares with the voltage converted from the
bottom MOSFET current. If the MOSFET current is high, the part enters the overcurrent
protection mode by turning off the top PWM MOSFET and holding the bottom MOSFET on. I
(mA) = 3120/RCS(kΩ).

PWM input pin. The PWM input signal is converted to a fixed 156-kHz switching frequency
on the MOSFET driver. The PWM input signal resolution is less than 1%. This pin can also
control the device and put it in or out of standby mode. After the signal at the PWM stays low
(up to 500 µs), the device goes into low-power standby mode. Standby current is
approximately 5 µA. The rising edge of the PWM signal wakes up the device and puts it into
active mode, where it is ready to start to turn the motor.

7 Detailed Description
7.1 Overview
DRV10866 is a 3-phase, sensorless motor driver with integrated power MOSFETs with drive current capability up
to 680-mA peak. DRV10866 is specifically designed for low noise, low external component count fan motor drive
applications. DRV10866 has built-in overcurrent protection with no external current sense resistor needed. The
synchronous rectification mode of operation achieves increased efficiency for motor driver applications.
DRV10866 can output either FG or ½ FG to indicate motor speed with open-drain output through FGS pin
selection. A 150° sensorless BEMF control scheme is implemented for a 3-phase motor. Voltage surge
protection scheme prevents input VCC capacitor from over charge during motor acceleration and deceleration
modes. DRV10866 has multiple built-in protection blocks including UVLO, overcurrent protection, lock protection
and thermal shutdown protection.

7.3 Feature Description
7.3.1 Speed Control
DRV10866 can control motor speed through either the PWMIN or VCC pin. Motor speed will increase with higher
PWMIN duty cycle or VCC input voltage. The curve of motor speed (RPM) vs PWMIN duty cycle or VCC input
voltage is close to linear in most cases. However, motor characteristics will affect the linearity of this speed
curve. DRV10866 can operate at very low VCC input voltage down to 1.65 V. The PWMIN pin is pulled up to VCC
internally and frequency range can vary from 15 kHz to 50 kHz. The motor driver MOSFETs will operate at
constant switching frequency 156 kHz. With this high switching frequency, DRV10866 can eliminate audible
noise and reduce the ripple of VCC input voltage and current, and thus minimize EMI noise.
7.3.2 Frequency Generator
The FG pin outputs a 50% duty cycle of PWM waveform in the normal operation condition. The frequency of the
FG signal represents the motor speed and phase information. The FG pin is an open-drain output, so an external
pullup resistor is needed when connected to an external system. During the start-up, FG output will stay at high
impedance until the motor speed reaches a certain level and BEMF is detected. During lock protection condition,
FG output will remain high until the motor restarts and start-up process is completed. DRV10866 can output
either FG or ½ FG to indicate motor status with open-drain output through FGS pin selection. When FGS is
pulled to VCC, the frequency of FG output is half of that when FGS is pulled to GND. Motor speed can be
calculated based on the FG frequency when FGS is pulled to GND, which equals to:
(FG ? 60)
RPM =
pole pairs
where
•
FG is in hertz (Hz).
(1)
7.3.3 Lock Protection
If the motor is blocked or stopped by an external force, the lock protection is triggered after lock detection time.
During lock detection time, the circuit monitors the PWM and FG signals. If PWM has an input signal while the
FG output is in high impedance during this period, the lock protection will be enabled and DRV10866 will stop
driving the motor. After lock release time, DRV10866 will resume driving the motor again. If the lock condition still
exists, DRV10866 will proceed with the next lock protection cycle until the lock condition is removed. With this
lock protection, the motor and device will not get over heated or be damaged.
7.3.4 Voltage Surge Protection
The DRV10866 has a unique feature to clamp the VCC voltage during lock protection and standby mode. If the
lock mode condition is caused by an external force that suddenly stops the motor at a high speed, or the device
goes into standby mode from a high duty cycle, either situation releases the energy in the motor winding into the
input capacitor. When a small input capacitor and anti-reverse diode are used in the system design, the input
voltage of the IC could rise above the absolute voltage rate of the chip. This condition either destroys the device
or reduces the reliability of the device. For this reason, the DRV10866 has a voltage clamp circuit that clamps the
input voltage at 5.95 V, and has a hysteresis of 150 mV. This clamp circuit is only active during the lock
protection cycle or when the device enters standby mode. It is disabled during normal operation.
7.3.5 Overcurrent Protection
The DRV10866 can adjust the overcurrent point through an external resistor connected to the CS pin (pin 9) and
ground. Without this external current sense resistor, the DRV10866 senses the current through the power
MOSFET. Therefore, there is no power loss during the current sensing. The current sense architecture improves
the overall system efficiency. Shorting the CS pin to ground disables the overcurrent protection feature. During
overcurrent protection, the DRV10866 only limits the current to the motor; it does not shut down the device. The
overcurrent limit can be set by the value of current sensing resistor through Equation 2.

Feature Description (continued)
7.3.6 Undervoltage Lockout (UVLO)
The DRV10866 has a built-in UVLO function block. The hysteresis of UVLO threshold is 150 mV. The device will
be locked out when VCC reaches 1.65 V and woke up at 1.8 V.
7.3.7 Thermal Shutdown
The DRV10866 has a built-in thermal shunt down function, which will shut down the device when the junction
temperature is over 160°C and will resume operating when the junction temperature drops back to 150°C.
7.4 Device Functional Modes
7.4.1 Start-up
At start-up with motor at standstill, commutation logic starts to drive the motor in open-loop with U-phase high, Vphase low, and the W-phase shut off. During open-loop start-up phase, commutation logic advance to next state
automatically as per Table 1 with duty cycle of 100% regardless of PWM input. At each state, commutation logic
detects zero-crossing of back-emf at shut-off phase. Once motor reaches to sufficient speed to allow four
consecutive successful back-emf zero-crossing, commutation logic switches to closed-loop operation mode as
explained in next section.
In certain cases, the motor may have initial speed in forward direction when the device attempts to start-up the
motor again. When this occurs, device commutation logic jumps over the open-loop start-up process and goes to
closed loop directly. By re-synchronizing to the spinning motor, the user achieves the fastest possible start-up
time for this initial condition.
7.4.2 Motor Running at Steady-State Speed
Once open-loop acceleration phase is over, motor steady state speed is determined by applied duty-cycle at
PWM input. In this mode, communication logic steps thought the six states mentioned in Table 1 and next
commutation state is determined by actual back-emf zero-crossing event at shut-off phase. Each state remains
for 150°. This is an advanced trapezoidal method that allows the device to drive the phases gradually to the
maximum current and gradually to 0. Commutation logic also provides the required 15° angle-advance from zerocrossing events to efficiently commutate the motor.
For a given duty-cycle input, motor speed can be different depending upon the motor loading conditions. Device
provides motor speed information at FG pin which can be used to achieve closed-loop speed control to get
constant speed at varying load condition.
7.4.3 Motor Stopping
Motor can be decelerated gradually by slowly reducing the PWM duty command to avoid overvoltage at DC
input. When the device is commanded to decelerate very fast or stop the motor suddenly from high speed, in
order to protect the IC and the system, the DRV10866 goes into AVS protection, as explained in Voltage Surge
Protection.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
DRV10866 only requires three external components. The device needs a 2.2-μF or higher ceramic capacitor
connected to VCC and ground for decoupling. During layout, the strategy of ground copper pour is very important
to enhance the thermal performance. For two or more layers, use eight thermal vias. Refer to Layout Example for
an example of the PCB layout. If there is no COM pin on the motor, one can be simulated. Use three resistors
connected in a wye formation, one connected to U, one to V, and one to W. Connect the resistor ends opposite
of the phases together. This center point is COM. To find the proper resistor value, start with a value of 10 kΩ
and continue to decrease by 1 kΩ until the motor runs properly.

9 Power Supply Recommendations
The DRV10866 is designed to operate from an input voltage supply, VCC, range from 1.65 V to 5.5 V. The user
must place a 2.2-μF ceramic capacitor rated for VCC as close as possible to the VCC and GND pin. If the power
supply ripple is more than 100 mV, in addition to the local decoupling capacitors, a bulk capacitance is required
and must be sized according to the application requirements. If the bulk capacitance is implemented in the
application, the user can reduce the value of the local ceramic capacitor to 220 nF.
10 Layout
10.1 Layout Guidelines
The DRV10866 is simple to design with a single-layer or two layer printed-circuit-board (PCB) layout. During
layout, the strategy of ground copper pour is very important to enhance the thermal performance. Use vias on
the thermal pad to dissipate heat away from the IC. Refer to Figure 18 for an example of PCB layout.
• Place VCC, GND, U, V, and W pins with thick traces because high current passes through these traces.
• Place the 2.2-μF capacitor between VCC and GND, and as close to the VCC and GND pins as possible.
• Connect the GND under the thermal pad.
• Keep the thermal pad connection as large as possible, both on the bottom side and top side. It should be one
piece of copper without any gaps.
