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.

DETAILED DEVICE DESCRIPTION
DRV10866 is a three 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 over current 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 three 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, over current protection,
lock protection and thermal shut down protection.
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.
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
pull up resistor is needed when connected to an external system. During the startup, 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 startup 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)
pole pairs
RPM =
(1)
Where FG is in hertz (Hz).
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.

SBVS206 –NOVEMBER 2012
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.
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.
3120
I (A) =
RCS (W)
(2)
UVLO (Undervoltage Lockout)
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.
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.

APPLICATION INFORMATION
The DRV10866 only requires three external components. A 2.2-µF or higher ceramic capacitor connected to VCC
and ground is needed for decoupling purposes. This capacitor must be placed close to the VCC pin (pin 3) and
GND pin (pin 5). During normal operation, a sudden drop in motor speed (caused by changing the PWM duty
from high to low immediately) causes the VCC voltage to rise to a very high level, especially when an anti-reverse
diode is added on the VCC side. In order to avoid this condition, a larger input capacitor between VCC and GND is
needed, along with removing the anti-reverse diode. The DRV10866 is simple to design with a single-layer
printed circuit board (PCB) layout. During layout, the strategy of ground copper pour is very important to enhance
the thermal performance. Refer to Figure 1 for an example of PCB layout.

Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
