LV8139JA
Sine wave PWM Drive, Pre drive IC,
for Brushless Motor Drive
Overview
The LV8139JA is a PWM system pre driver IC designed for three-phase
brushless motors.
This IC reduces motor driving noise by using a high-efficiency, sine wave
PWM drive type.
It incorporates a full complement of protection circuits and, by combining it
with a hybrid IC in the STK611 or STK5C4 series, the number of components
used can be reduced and a high level of reliability can be achieved.
Furthermore, its power-saving mode enables the power consumption in the
standby mode to be reduced to zero. This IC is optimally suited for driving
various large-size motors such as those used in air conditioners and hot-water
heaters.
Features
• Three-phase bipolar drive
• Sine wave PWM drive
• Drive phase setting function (Set 0-58 degrees 32 steps: There is an adjustment
function corresponding to the CTL pin input)
• Supports power saving mode(power saving mode at CTL pin voltage of 0.95V
(typ) or less; ICC = 0mA, HB pin turned off)
• Supports bootstrap
• Automatic recovery type constraint protection circuit
• Forward/reverse switching circuit, Hall bias pin
• Current limiter circuit, low-voltage protection circuit, and thermal shutdown
protection circuit
• FG1 and FG3 output (360-degree electrical angle/1 pulse and 3 pulses)
Typical Applications
• Air Purifier
• Clothes Dryer
• Air conditioners
• Consumer

Functional Description
Basic operation of 120-degree Sine wave
current-carrying switching
At startup, this IC starts at 120-degree
current-carrying. The current-carrying is switched to
sine wave when the 3-Hall FG frequency is 5.15Hz
(typ) or above and the rising edge of the IN2 signal has
been detected twice in succession.
the Hall signal input sequence
Concerning
This IC controls the motor rotation direction
commands and Hall signal input sequence in order to
set the lead angle. If the motor rotation direction
commands and Hall signal input sequence do not
conform to what is shown on the timing chart, the
motor is driven by 120-degree current-carrying.
Shown below are two Hall signal input sequences.

CTL pin input
a) Power-saving mode VCTL VIL (0.95V : typ)
LIN1 to LIN3 and HIN1 to HIN3 outputs all set to
low
ICC = 0, HB pin = OFF
The power consumption of the IC can now be set to
0, and the power consumption of the Hall element
connected to the HB pin and the output block can
also be set to 0.
The CTL pin is pulled down by 170k (120-degree
mode) : Typ, 131.6k (sine wave mode) : typ inside
the IC. Caution is required when the control input
voltage input is subjected to resistance division, for
example.
b) Standby mode While stopped: VIL VCTL
VIM1 (2.33V: typ); while running: VIL VCTL
VIM2 (2.1V: typ)
The UIN1 to 3 outputs are set to low, and the
bootstrap charge pulse (pulse width: 2.5s: design
target) is output to the LIN1 to 3 outputs in
preparation for drive start.
Bootstrap capacitor initial charging mode
When the mode is switched from the power-saving
mode to the standby mode and then to the drive mode,
the IC enters the bootstrap capacitor charging mode
(HIN1, HIN2, HIN3 pins = L LIN1, LIN2, LIN3 pins
= H 4.55ms typ) in order to charge the bootstrap
capacitor.
* When the PWM oscillation frequency setting is
17kHz, the maximum duty ratio in the 120-degree
current carrying mode is 88% (typ).
c) Drive mode At drive start: VIM1 VCTL 7V;
during drive: VIM2 VCTL 7V (VIH 4.7V: typ)
The motor is driven at the PWM duty ratio that
corresponds to VCTL. When VCTL is increased,
the PWM duty ratio increases, and the maximum
duty ratio is established at “VIH.”
d) Test mode 8.5V VCTL VCC
When the CTL pin voltage is 8V or higher, the IC
enters the test mode, and the motor is driven at the
120-degree current-carrying and maximum duty*
ratio.

Drive phase adjustment
During 180-degree current-carrying drive, any lead
angle from 0 to 58 degrees can be set using the ADP1
pin voltage (lead angle control). This setting can be
adjusted in 32 steps (in 1.875-degree increments) from
0 to 58 degrees using the ADP1 pin voltage, and it is
updated every Hall signal cycle (it is sampled at the
rising edge of the IN3 input and updated at its falling
edge).
A number of lead angle adjustments proportionate to
the CTL pin voltage can be undertaken by adjusting
the resistance levels of resistors connected to the
ADP1 pin, ADP2 pin and DPL pin. When these pins
are not going to be used, reference must be made to
section 4.5, and the pins must not be used in the open
status. Furthermore, a resistance of 47k or more
must be used for the resistor (RADP2) that is
connected to the ADP2 pin.
1. The slopes of VCTL and VADP1 can be adjusted by
setting the resistance level of the resistor (RADP1)
connected to ADP1 (pin 15).

Description of LV8139
1. Current Limiter Circuit
The current limiter circuit limits the output current
peak value to a level determined by the equation I =
VRF/Rf (where VRF = 0.25V typ, Rf is the value of
the current detection resistor). The current limiter
operates by reducing the HIN output on duty to
suppress the current.
The current limiter circuit detects the reverse
recovery current of the diode due to PWM operation.
To assure that the current limiting function does not
malfunction, its operation has a delay of approx. 1s.
If the motor coils resistance or a low inductance,
current fluctuation at startup (when there is no back
electromotive force in the motor) will be rapid. The
delay in this circuit means that at such times the
current limiter circuit may operate at a point well
above the set current. Application must take this
increase in the current due to the delay into account
when the current limiter value is set.
2. Power Saving Circuit (CTL pin)
This IC goes into the power saving mode that stops
operation of all the circuits to reduce the power
consumption. If the HB pin is used for the Hall
element bias and the output block, the current
consumption in the power-saving mode is zero.
3. Hall Input Signal
Signals with an amplitude in excess of the hysteresis
is required for the Hall inputs. However, considering
the influence of noise and phase displacement, an
amplitude of over 100mV is desirable.
If noise disrupts the output waveform, this must be
prevented by inserting capacitors or other devices
across the Hall inputs. The Hall inputs are used by the
circuit inside the IC as decision signals so if noise
enters, a malfunction occurs in the operation.
Although the circuit is designed to tolerate a certain
amount of noise, care is required.
Furthermore, when the Hall signal amplitude has
changed as a result of a change in temperature, the
drive phase may possibly shift due to the Hall
amplifier hysteresis. It is the user who is responsible
for giving due consideration to this aspect. Use of a
Hall IC is recommended unless there is a reason not
to use one.
If all three phases of the Hall input signal go to the
same input state (HHH or LLL), all the HIN/LIN
outputs are set to low.
If the outputs from a Hall IC are used, fix one side of
the inputs (either the “+” or “−” side) at a voltage
within the common-mode input voltage range (0.3V
to VREG–1.8V), and use the other input side as an
input over the 0V to VREG range.
4. Constraint Protection Circuit
A constraint protection circuit is incorporated in
order to protect the output elements and motor when
the motor is constrained. The circuit is activated
when the Hall signal is not switched for a specific
period of time when the motor is in operation. The
counter is reset each time the motor rotates 360
degrees in terms of the electrical angle.
All the HIN and LIN outputs are set to the low level
when the constraint protection circuit is in operation.
This time is determined by the capacitance of the
capacitor connected to the CSD pin.
Oscillation time of CSD pin (1 pulse) T =
(VOH-VOL)/ICHG1 C (F) +
(VOH-VOL)/ICHG2 C (F)
Constraint protection detection time T1 (s) = T 256
(count)
Constraint protection time T2 (s) = T 2816 (count)
When a 0.022F capacitor is attached, T = 8.36ms,
T1 = 2.14s and T2 = 23.54s are established as the
typical ratings. After the motor has been constrained,
the constraint protection state is established at 2.14
(s), and then after 23.54 (s) has elapsed, the constraint
protection circuit is reset automatically. A time that
provides some leeway in the motor start time that
factors in any fluctuations must be selected as the
setting.
Conditions for releasing the constraint protection
state other than by automatic resetting:
When CTL pin voltage VIM2 input
protection release and CSD count reset
When the low level is detected on the TH pin
protection release and CSD count reset
When FR has been switched protection release
and CSD count reset
When TSD protection is detected CSD count
stop
5. Power Supply Stabilization
Since this IC adopts a switching drive technique, the
power-supply line level can be disrupted easily. Thus
capacitors large enough to stabilize the power supply
voltage must be inserted between the VCC pins and
ground. If the electrolytic capacitors cannot be
connected close to their corresponding pins, ceramic
capacitors of about 0.1F must be connected near
these pins.
If diodes are inserted in the power-supply line to
prevent destruction of the device when the power
supply is connected with reverse polarity, the power
supply line levels will be even more easily disrupted,
and even larger capacitors must be used.

LV8139JA
6. VREG Stabilization
Connect a capacitor with a capacitance of 0.1F or
more between VREG5 and ground in order to
stabilize the VREG voltage that is the power supply
of the control circuit.
The ground lead of that capacitor must be located as
close as possible to the control system ground
(SGND) of the IC.
7. Forward/Reverse Switching (F/R pin)
Switching between forward rotation and reverse
rotation must not be undertaken while the motor is
running.
8. TH Pin
The TH pin must normally be pulled up to VREG5
for use. When this pin has been set to low, all the
HIN/LIN outputs are set to low. When reset is
initiated, the bootstrap initial charging mode is
established.
The drive phase is shifted.
The motor has been suddenly accelerated.
The output duty ratio has been decreased sharply
while the motor is running.
If the output duty ratio has been decreased sharply, it
is highly likely that current will return to the motor
power supply.
The extent to which the motor supply voltage
increases differs depending on the size of the
capacitors used in the product that incorporates the
motor, the size of the capacitor inserted between the
motor power supply and ground on the motor circuit
board and the motor used; as such, it is the user who
is responsible for giving due consideration to this
aspect.
It is necessary to take remedial action such as
increasing the capacitance of the capacitors or
reducing the speed at which the duty ratio will be
reduced when the motor supply voltage rises to
ensure that the maximum withstand voltage of the
element used for output is not exceeded.
9. FAULT Pin
The FAULT pin must normally be pulled up to
VREG5 for use. When this pin has been set to low, all
the HIN/LIN outputs are set to low. When reset is
initiated, the bootstrap initial charging mode is
established.
All the outputs are set to low. In addition, the
FG1/FG3 output goes off, too. When reset is initiated,
the bootstrap initial charging mode is established.
10. PWM Frequency Setting
fCPWM 1/ (1.7CR)
Components with good temperature characteristics
must be used.
An oscillation frequency of about 17kHz is obtained
when a 2200pF capacitor and 15k resistor are used.
If the PWM frequency is too low, switching noise
will be heard from the motor; conversely, if it is too
high, the output power loss will increase. For this
reason, a frequency between 15kHz and 30kHz or so
is desirable. The capacitor ground must be connected
as close as possible to the control system ground
(SGND pin) of the IC to minimize the effects of the
outputs.
If there are no fluctuations in the capacitance or
resistance of the external capacitors or resistors and
only the IC fluctuations are to be considered, an
actual capability of 3% can be expected.
11.Concerning the power-raising operation
This IC provides sine wave PWM drive so it
performs operations similar to synchronous
rectification. These operations are such that current is
sometimes returned to the motor power supply side
depending on the conditions of use. For instance, this
may happen when:
