LB11696V
LB11696V FUNCTIONAL DESCRIPTION
1. Output Drive Circuit:
The LB11696V adopts direct PWM drive to
minimize power loss in the outputs. The output
transistors are always saturated when on, and the
motor drive power is adjusted by changing the on
duty of the output. The output PWM switching is
performed on the UH, VH, and WH outputs. Since
the UL to WL and UH to WH outputs have the
same output form, applications can select either
low side PWM or high side PWM drive by
changing the way the external output transistors
are connected. Since the reverse recovery time of
the diodes connected to the non-PWM side of the
outputs is a problem, these devices must be
selected with care. (This is because through
currents will flow at the instant the PWM side
transistors turn on if diodes with a short reverse
recovery time are not used.)
2. Current Limiter Circuit:
The current limiter circuit limits the output current
peak value to a level determined by the equation
I = VFR/Rf (VRF = 0.25 V typical, Rf: current
detection resistor). This circuit suppresses the
output current by reducing the output on duty.
To get shorter the distance between Rf and RF pin
and RF GND, to get the measurement more
precisely.
The current limiter circuit includes an internal
filter circuit to prevent incorrect current limiter
circuit operation due to detecting the output diode
reverse recovery current due to PWM operation.
Although there should be no problems with the
internal filter circuit in normal applications,
applications should add an external filter circuit
(such as an RC low-pass filter) if incorrect
operation occurs (if the diode reverse recovery
current flows for longer than 1 ms).

To S/S
Hall
4. Notes on the PWM Frequency:
The PWM frequency is determined by the
capacitor C (F) connected to the PWM pin.
fPWM ≈ 1 / (22500 × C)
If a 2000 pF capacitor is used, the circuit will
oscillate at about 22 kHz. If the PWM frequency is
too low, switching noise will be audible from the
motor, and if it is too high, the output power loss
will increase. Thus a frequency in the range
15 kHz to 50 kHz must be used. The capacitor’s
ground terminal must be placed as close as
possible to the IC’s ground pin to minimize the
influence of output noise and other noise sources.
5. Control Methods:
The output duty can be controlled by either of the
following methods:
• Compare TOC Voltage and PWM Waveform:
The low side output transistor duty is
determined by the result of comparing the TOC
pin voltage to the PWM oscillator waveform.
When the TOC voltage is 1.35 V or lower, the
duty is set to 0% and when the TOC voltage is
3.0 V or higher, it is set to 100%. Because the
TOC pin is the output of the CTL amplifier, it is
not able to input the control voltage into it.
Hence, CTL amplifier is used as an all feedback
amplifier (connect the EI- and the TOC pin) and
DC voltage should be input through the EI+ pin
(the EI+ pin = the TOC pin voltage). The
increase of EI+ voltage increases the output
duty and when EI+ is open, the motor is in
rotation. To stop the motor rotation, the
pull-down register should be connected to EI+
pin.
When the TOC pin voltage control is used,
a low-level input must be applied to the
PWMIN pin or that pin connected to GND.
• Pulse Control Using the PWMIN Pin:
A pulse signal can be input to the PWMIN pin,
and the output can be controlled by the duty of
that signal.
The output is on when a low level is input to
To the RF Pin

3. Power Save Circuit:
For this IC, the state of motor stop is power save
mode to decrease the power consumption. In this
mode, almost all of the circuit are off, though
VREG (5 V) output is active. If the bias current of
Hall element should be off, connect Hall element
and 5 V through PNP Tr.
www.onsemi.com

VCC Pin
the PWMIN pin, and off when a high level is
input. When the PWMIN pin is open, the pin
goes to the high level and the output is turned
off. If inverted input logic is required, an
external transistor (NPN) can allow it.
When controlling motor operation from the
PWMIN pin, the EI- pin must be connected to
the GND and the EI+ pin must be connected to
the TOC pin.
Note that since the PWM oscillator is also used
as the clock for internal circuits, a capacitor
(about 2000 pF) must be connected to the PWM
pin even if the PWMIN pin is used for motor
control.
6. Hall Input Signals:
A signal input with an amplitude in excess of the
hysteresis (80 mV maximum) is required for the
Hall inputs.
Considering the possibility of noise and phase
displacement, an even larger amplitude is
desirable.
If disruptions to the output waveforms (during
phase switching) or to the HP output (Hall signal
output) occur due to noise, this must be prevented
by inserting capacitors across the inputs.
The constraint protection circuit uses the Hall
inputs to discriminate the motor constraint state.
Although the circuit is designed to tolerate
a certain amount of noise, care is required when
using the constraint protection circuit.
If all three phases of the Hall input signal system
go to the same input state, the outputs are all set to
the off state (the UL, VL, WL, UH, VH, and WH
outputs all go to the low level).
If the outputs from a Hall IC are used, fixing one
side of the inputs (either the + or – side) at
a voltage within the common-mode input voltage
range allows the other input side to be used as an
input over the 0 V to VCC range.
7. Under-voltage Protection Circuit:
The under-voltage protection monitors the LVS
pin voltage and the circuit turns off the outputs
(UH, VH, and WH) when the voltage falls below
the minimum operation voltage (see the Electrical
Characteristics). To prevent the reputation of the
output on and off close to the protection threshold
voltage, it has hysteresis which is 0.45 V (typical).
Hence to release the protection mode, plus 0.45 V
(typ.) to the operation voltage is needed.
To LVS Pin
The detection level of the protection voltage is 5 V
system. If it is needed to go up the detection level,
connect the Zenner diode to LVS pin in series to shift
the detection voltage level. The LVS input current
for the detection is about 75 mA. To increase the
current of the Zenner diode to stabilize the rising
voltage of it, insert the resistor between LVS pin and
GND.
When the LVS pin is open, it becomes GND level
and the output is off because of pull-down resistor
inside the circuit. Hence, when it turns off, the
voltage higher than 4.35 V should be input to LVS
pin as a release voltage. The maximum ratings of
LVS pin is 18 V.
8. Constraint Protection Circuit:
When the motor is physically constrained (held
stopped), the CSD pin external capacitor is
charged (to about 3.0 V) by a constant current of
about 2.5 mA and is then discharged (to about
1.0 V) by a constant current of about 0.14 mA.
This process is repeated, generating a saw-tooth
waveform. The constraint protection circuit turns
motor drive on and off repeatedly based on this
saw-tooth waveform. (The UH, VH, and WH side
outputs are turned on and off.) Motor drive is on
during the period the CSD pin external capacitor is
being charged from about 1.0 V to about 3.0 V,
and motor drive is off during the period the CSD
pin external capacitor is being discharged from
about 3.0 V to about 1.0 V.
The IC and the motor are protected by this
repeated drive on/off operation when the motor is
physically constrained.
The motor drive on and off times are determined
by the value of the connected capacitor C (in mF).
TCSD1 (drive on period) ≈ 0.8 × C (seconds)
TCSD2 (drive off period) ≈ 14.3 × C (seconds)
When a 0.47 mF capacitor is connected externally
to the CSD pin, this iterated operation will have
a drive on period of about 0.38 seconds and a drive

off period of about 6.7 seconds.
While the motor is turning, the discharge pulse
signal (generated once for each Hall input period)
that is created by combining the Hall inputs
internally in the IC discharges the CSD pin
external capacitor. Since the CSD pin voltage does
not rise, the constraint protection circuit does not
operate.
When the motor is physically constrained, the Hall
inputs do not change and the discharge pulses are
not generated.
As a result, the CSD pin external capacitor is
charged by a constant current of 2.5 mA to about
3.0 V, at which point the constraint protection
circuit operates. When the constraint on the motor
is released, the constraint protection function is
released.
Connect the CSD pin to ground if the constraint
protection circuit is not used.
9. Forward/Reverse Direction Switching:
This IC is designed so that through currents
(due to the output transistor off delay time when
switching) do not flow in the output when
switching directions when the motor is turning.
However, if the direction is switched when the
motor is turning, current levels in excess of the
current limiter value may flow in the output
transistors due to the motor coil resistance and the
motor back EMF state when switching. Therefore,
designers must consider selecting external output
transistors that are not destroyed by those current
levels or only switching directions after the speed
has fallen below a certain speed.
10. Handling Different Power Supply Types:
When this IC is operated from an externally
supplied 5 V power supply (4.5 to 5.5 V), short the
VCC pin to the VREG pin and connect them to the
external power supply.
When this IC is operated from an externally
supplied 12 V power supply (8 to 17 V), connect
the VCC pin to the power supply. (The VREG pin
will generate a 5 V level to function as the control
circuit power supply.)
11. Power Supply Stabilization:
Since this IC uses a switching drive technique, the
power supply line level can be disturbed easily.
Therefore capacitors with adequate capacitance to
stabilize the power supply line must be inserted
between VCC and ground.
If diodes are inserted in the power supply lines to
prevent destruction if the power supply is
connected with reverse polarity, the power supply
lines are even more easily disrupted, and even
larger capacitors are required.
If the power supply is turned on and off by
a switch, and if there is a significant distance
between that switch and the stabilization capacitor,
the supply voltage can be disrupted significantly
by the line inductance and surge current into the
capacitor. As a result, the withstand voltage of the
device may be exceeded. In application such as
this, the surge current must be suppressed and the
voltage rise prevented by not using ceramic
capacitors with a low series impedance, and by
using electrolytic capacitors instead.
12. VREG Stabilization:
To stabilize the VREG voltage, which is the
control circuit power supply, a 0.1 mF or larger
capacitor must be inserted between the VREG pin
and ground. The ground side of this capacitor must
connected to the IC ground pin with a line that is
as short as possible.
