Overview
The LV88561JA/R, LV88562JA/R, LV88563JA/R and
LV88564JA/R are the pre−driver for a single−phase 24 V/48 V BLDC
motor, which have the closed loop controller for motor rotation speed.
These are available to control a motor with low vibration and the low
noise. In addition, lead−angle adjustment is possible by external pins.
Lead−angle value and lead−angle slant can be adjusted independently.
Thus, the device can be driven by high efficiency and low noise with
various motors. Motor speed setting curve is adjustable with using
external resistor only. As a method of the rotary speed control of the
motor, direct−PWM pulse input is adopted.

FUNCTIONAL DESCRIPTION
Loop Gain
Command Input (PWM)
Motor speed loop gain of LV88563 and LV88564 is lower
than that of LV88561 and LV88562. If the motor coil current
generate large overshoot during motor speed transition,
LV88563 and LV88564 can reduce the overshooting current
but the motor rotation response speed will decrease.
LV88561 and LV88562 are recommended if faster response
speed is required.
This pin reads the duty cycle of the PWM pulse and
controls rotational speed. The PWM input signal level is
supported from 2.5 V to 5 V. The combination with the
rotational speed control by DC voltage, is impossible.
When the pin is not used, it must be connected to ground.
The minimum pulse width is 100 ns.
Current Sense Resistor Pin (RF)
Since Power FET side ground line has to tolerate surge of
current, separate it from the GND pin as far away as possible
and connect it point−to−point to the ground side of the
capacitor (C0) between VCC and GND.
LV8856xJA/R provides the dynamic lead angle
adjustment. To match the motor characteristics, set two
point lead−angel, low speed side (set by LAI pin) and high
speed side(set by LAG pin).
At middle range of input duty, the lead−angle iis applied
to calculated value for relative relationship.
The DC voltage levels applied to these pins are converted
to the lead angle parameter. The voltages are fetched right
after the power−on−reset. Because the internal conversion
circuit works inside REG power rail, it is recommended that
the LAI and LAG voltages are made from VREG.
Internal 5.0 V Voltage Regulator Pin (REG, VDD)
Rotation Speed Setting Pin (RSA, RSB)
REG is internal 5.0 V voltage regulator.
VDD is power supply for internal logic, oscillator, and
protection circuits. Please connect REG and VDD.
When PIX, PIZ, RSA, RSB, LAI, LAG and SFS are used,
it is recommended that application circuits are made using
this output. The maximum load current of REG is 20 mA.
Don’t exceed this value. Place capacity from 0.1 mF to
1.0 mF in the close this pin.
LV8856xJA/R provides the feedback speed control, so
this device can set the rotation speed value (RPM) directly.
To make the motor speed setting curve, set two point
rotation speed value, high speed side and low speed side.
The DC voltage levels applied to these pins are converted
to the rotation speed parameter. The voltages are fetched
right after the power−on−reset. Because the internal
conversion circuit works inside REG power rail, it is
recommended that the RSA and RSB voltages are made
from VREG.
Lead−Angle Setting Pin (LAI, LAG)
RF is current sense input terminal.
Voltage across the sense resistor represents the motor
current and is compared against the internal VTHOVC (0.10
Vtyp.) for setting the over−current limiter (CLM).
VCC and GND Pin (VCC ,GND)
Rotational Signal Pin (FG)
This is an open drain output pin which outputs the
rotational signal. In case of LV88561 and LV88563, FG
signal will come out from this pin and its frequency will
represent electrical speed of a motor.
In case of LV88562 and LV88564, RD signal will come
out from this pin. See page 21 ”Lock detection and Lock
protection” for more information about the RD signal.
Recommended pull up resistor value is 1 kW to 100 kW.
Leave the pin open when not in use.
Rotation Speed Curve Duty Setting Pin (PIX, PIZ)
To make the motor speed setting curve, set two point input
duty parameter, high speed side and low speed side.
The DC voltage levels applied to these pins are converted
to the input duty parameter. The voltages are fetched right
after the power−on−reset. Because the internal conversion
circuit works inside REG power rail, it is recommended that
the PIX and PIZ voltages are made from VREG.
Soft−Start and Dead Time Setting Pin (SFS)
Output Pins for External FET Control (O1H , O1L ,
O2H, O2L)
LV8856xJA/R provides synchronous rectification drive
for high efficiency drive. External FET size is variable
caused by the motor application. So this driver IC is able to
choose 2 types of dead time.
Soft start function pattern is able to choose from 16 types.
The DC voltage levels applied to these pins are converted
to the soft−start setting and dead time parameter. The voltage
is fetched right after the power−on−reset. Because the
internal conversion circuit works inside REG power rail, it
is recommended that the SFS voltage is made from VREG.
These pins are output for external MOSFET. O1H and
O2H connect to upper side P−ch FET’s gate−line. O1L and
O2L connect to lower side N−ch FET’s gate line.
Hall−Sensor Input Pins (IN1, IN2)
Differential output signals of the hall sensor are to be
interfaced at IN1 and IN2. It is recommended that 0.01 mF
capacitor is connected between both pins to filter system
noise.
When a Hall IC is used, the output of the Hall IC must be
connected to the pin IN1. And, the pin IN2 must be kept in
the middle level of the Hall IC power supply voltage.

DETAILED DESCRIPTION
When the input duty is lower than LSP setting duty, the
LV8856xJA/R can select “motor stop” or “keep LSP
rotation speed”.
When the input duty is higher than HSP setting duty, the
LV8856xJA/R can select “free run” or “keep HSP rotation
speed”.
Rotation speed of LSP and HSP is set by RSA and RSB
pin. The case of RSA > RSB, “motor stop” mode applied.
The case of RSA < RSB, “keep LSP rotation speed” mode
applied.
Input duty of LSP and HSP is set by PIX and PIZ pin. The
case of PIX > PIZ, “free run” mode applied. The case of PIX
< PIZ, “keep HSP rotation speed” mode applied.
So LV8856xJA/R can’t set decease speed curve at input
duty increase.
Figures 21 − 24 show setting curve example.
As for all numerical value used in this description, the
design value or the typical value is used.
Rotation Speed Curve Setting Description
The LV8856xJA/R can set 2 points speed parameter
arbitrarily.
Low speed point (LSP)
High speed point (HSP)
At middle range of input duty, the rotation speed is applied
to calculated value for relative relationship.

Soft−Start Setting Description
When reached to the release condition, change to closed−
loop speed control mode.
If the motor can’t rotation during 0.7s (typ), lock
protection function will activate.
The recommendation of soft−start time is 1.72 s. Hence,
it can be set by A−D code “0” and “31” for easy
implementation by pin pull−down or pull−up.
LV8856xJA/R has soft start function.
To avoid the motor rush current, the output PWM duty
rise−up from zero slowly at the starting of motor rotation.
The soft start action release conditions are below;
Rotation speed reach to target speed decided by PWM
input.
Output duty reach to “Release duty”.

Output Waveform
LV8856xJA/R output PWM frequency is fixed by the
inner oscillator parameter, 48 kHz (typ) which doesn’t
depend on input PWM frequency.
Driving method of LV8856xJA/R uses PWM soft
switching drive.
Soft switching width is changed by input PWM duty.
When the input duty is HSP setting duty, soft switching
width is narrow (S/L = 20.5%)
On the other hand when the input duty is LSP setting duty,
soft switching width becomes wide (S/L = 46.9%)
TIME

In this part, the rise/fall time of soft switching waveform
is equal. Therefore, the “S” in the figure can be also applied
to fall time as well.

Current Limiter (CLM)
At the middle range input duty, the soft switching width
is applied to calculated value for relative relationship.
When the coil current increases and the voltage of the RF
pin rises to 0.1 V (typ), the CLM operates and shut the coil
current.
CLM current is adjustable by resistor value between
RF−GND.
The sense resistor value is calculated as follows.
Protections
LV8856xJA/R has some protection function.
− Thermal shutdown protection (TSD)
− Under voltage lock out (UVLO)
− Current limiter (CLM)
− Lock protection
When TSD or Lock protection is working, external FETs
are all turned off.
On the other hand, when UVLO or CLM is working,
output is turned off and goes into re−circulation state.

When this IC’s junction temperature rises to 180°C (typ),
O1H/O2H output turns to high, and O1L/O2L output turn to
low. External FETs are all turns off and coil current is shut
off.
Next, when IC’s junction temperature falls to 140°C (typ),
thermal shutdown function is released and motor starts to
rotate.
(eq. 6)
Lock Detection and Lock Protection
When the motor lock is happened, heat is generated
because IC continues to supply electricity to the motor. And
IC detects this radiated heat and turns off the electricity to the
motor.
If IC does not receive the FG edge for 0.3sec (under
50rpm), the IC judges ”motor lock” has occurred and the
lock protection function will activate. In this mode, the RD
signal goes to ”High”, though it is ”Low” at motor starts.
When the motor restarts and IC detects 4 phase changes,
the RD signal goes to ”Low”.

It takes 3.5s for Lock protection time(1st to 4th protection
time). This equals to the total of lock detection time and lock
protection time. The lock detection time – the ratio is approx.
1:5 (from 1st to 4th protection time).
After 5th protection time, the lock protection time
becomes 14s and protection−start time ratio is approx. 1:20
(after 5th protection time)
When the motor rotation is stopped by PWM input signal,
the lock detection is reset and the motor starts to rotate
smoothly once the IC receives the rotation start instruction.

PCB GUIDELINES
VCC and Ground Routing
(20−30 cm to 2−3 m), the battery voltage may overshoot
when the power is supplied due to the impact of the routing
of the inductance. Make sure that the voltage does not
exceed the absolute maximum standard voltage when the
power supply turns on.
These capacitance values are just for reference, so the
confirmation with the actual application is essential to
determine the values appropriately.
Make sure to short−circuit power line externally by a low
impedance route on one side of PCB. As high current flows
into external FET to GND, connect it to GND through a low
impedance route.
The capacitance connected between the VCC pin and the
opposite ground is to stabilize the battery. Make sure to
connect an electrolytic capacitor with capacitance value of
about 1 mF (0.1 mF or greater) to eliminate low frequency
noise. Also, to eliminate high frequency noise, connect a
capacitor of superior frequency characteristics, with
capacitance value of about 0.1 mF and make sure that the
capacitor is connected as close to the pin as possible. Allow
enough room in the design so the impact of PWM drive and
flyback do not affect other components. Especially, when
the coil inductance is large and/or the coil resistance is small,
current ripple will rise so it is necessary to use a
high−capacity capacitor with superior frequency
characteristics. Please note that if the battery voltage rises
due to the impact of the coil flyback as a result of the use of
diode for preventing the break down caused by reverse
connection, it is necessary to either increase the capacitance
value or place Zener diode between the battery and the
ground so that the voltage does not exceed its absolute
maximum voltage.
When the electrolytic capacitor cannot be used, add the
resistor with the value of about 1 W and a ceramic capacitor
with the capacitor value of about 10 mF in series for the
alternative use. When the battery line is extended,
RF Routing
Power current (output current) flows through the RF line.
Make sure to short−circuit the line from RF through GND as
well as GND. The RF resistance must choose enough power
rating.
External FET Output Pins
Since the pins have to tolerate surge of current, make sure
that the wires are thick and short enough when designing the
PCB board.
