Reducing the noise of hall signal
Hall element may be affected by Vcc noise or the like depending on the wiring pattern of board. In this case, place
a capacitor like C1 in Fig.9. In addition, when wiring from the hall element output to IC hall input is long, noise may
be loaded on wiring. In this case, place a capacitor like C2 in Fig.9.
Fig.9 Application near hall signal
This IC doesn’t have hall input hysteresis.
Note the hall input so that the FG signal do not chatter by the noise of the hall signal.

Safety measure
1) Reverse connection protection diode
Reverse connection of power results in IC destruction as shown in Fig.10. When reverse connection is possible, reverse
connection protection diode must be added between power supply and Vcc.
Fig.10 Flow of current when power is connected reversely
2) Measure against Vcc voltage rise by back electromotive force
Back electromotive force (Back EMF) generates regenerative current to power supply. However, when reverse
connection protection diode is connected, Vcc voltage rises because the diode prevents current flow to power supply.
Fig.11 Vcc voltage rise by back electromotive force
When the absolute maximum rated voltage may be exceeded due to voltage rise by back electromotive force, place
(A) Capacitor or (B) Zener diode between Vcc and GND. If necessary, add both (C).

3) Problem of GND line PWM switching
Do not perform PWM switching of GND line because GND terminal potential cannot be kept to a minimum.
Fig.13 GND Line PWM switching prohibited
4) FG and AL output
FG and AL output is an open collector and requires pull-up resistor.
The IC can be protected by adding resistor R1. An excess of absolute maximum rating, when FG or AL output
terminal is directly connected to power supply, could damage the IC.
Fig.14 Protection of FG and AL terminal
Calculation of power consumed by IC
Power consumed by this IC Pc is approximately calculated as follows:
Pc=Pc1+Pc2+Pc3
Pc1Power consumption by circuit current
Pc1=Vcc×Icc
Pc2Power consumption at output stage
Pc2=VOL×Io+VOH×Io
VOL is L voltage of output terminal 1 and 2.
VOH is H voltage of output terminal 1 and 2.
Io is the current flowing to output terminal 1 and 2.
Pc3Power consumption at AL
Pc3=VAL×IAL
VAL is L voltage of AL output.
IAL is the current of AL.
Power consumption by IC greatly changes with use condition of IC such as power supply voltage and output current.
Consider thermal design so that the maximum power dissipation on IC package is not exceeded.

Thermal derating curve
Power dissipation (total loss) indicates the power that can be consumed by IC at Ta = 25ºC (normal temperature). IC is
heated when it consumes power, and the temperature of IC chip becomes higher than ambient temperature. The
temperature that can be accepted by IC chip depends on circuit configuration, manufacturing process, etc, and consumable
power is limited. Power dissipation is determined by the temperature allowed in IC chip (maximum junction temperature)
and thermal resistance of package (heat dissipation capability). The maximum junction temperature is in general equal to
the maximum value in the storage temperature range.
Heat generated by consumed power of IC is radiated from the mold resin or lead frame of package. The parameter which
indicates this heat dissipation capability (hardness of heat release) is called heat resistance, represented by the symbol θ
ja [/W]. The temperature of IC inside the package can be estimated by this heat resistance. Fig.16 shows the model of
heat resistance of the package.
Heat resistance θja, ambient temperature Ta, junction temperature Tj, and power consumption P can be calculated by the
equation below:
θja (Tj - Ta) / P [/W]
Thermal derating curve indicates power that can be consumed by IC with reference to ambient temperature. Power that can
be consumed by IC begins to attenuate at certain ambient temperature. This gradient is determined by thermal resistance
θja.
Thermal resistance θja depends on chip size, power consumption, package ambient temperature, packaging condition,
wind velocity, etc., even when the same package is used. Thermal derating curve indicates a reference value measured at
a specified condition. Fig.17 shows a thermal derating curve (Value when mounting FR4 glass epoxy board 70 [mm] x 70
[mm] x 1.6 [mm] (copper foil area below 3 [%]))

Cautions on use
1) Absolute maximum ratings
Devices may be destroyed when supply voltage or operating temperature exceeds the absolute maximum ratings. Because the
cause of this damage cannot be identified as a short circuit or an open circuit, if any over rated values will expect to exceed the
absolute maximum ratings, consider adding circuit protection devices, such as fuses..
2) Connecting the power supply connector backward
Connecting of the power supply in reverse polarity can damage IC. Take precautions when connecting the power
supply lines. An external direction diode can be added.
3) Power supply line
Back electromotive force causes regenerated current to power supply line, therefore take a measure such as placing
a capacitor between power supply and GND for routing regenerated current. And fully ensure that the capacitor
characteristics have no problem before determine a capacitor value. (when applying electrolytic capacitors,
capacitance characteristic values are reduced at low temperatures)
4) GND potential
It is possible that the motor output terminal may deflect below GND terminal because of influence by back
electromotive force of motor. The potential of GND terminal must be minimum potential in all operating conditions,
except that the levels of the motor outputs terminals are under GND level by the back electromotive force of the motor
coil. Also ensure that all terminals except GND and motor output terminals do not fall below GND voltage including
transient characteristics. Malfunction may possibly occur depending on use condition, environment, and property of
individual motor. Please make fully confirmation that no problem is found on operation of IC.
5) Thermal design
Use a thermal design that allows for a sufficient margin in light of the power dissipation(Pd) in actual operating
conditions.
6) Inter-pin shorts and mounting errors
Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any
connection error or if pins are shorted together.
7) Actions in strong electromagnetic field
Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to
malfunction.
8) ASO
When using the IC, set the output transistor so that it does not exceed absolute maximum rations or ASO.
9) Thermal shut down circuit
The IC incorporates a built-in thermal shutdown circuit (TSD circuit). Operation temperature is 175(typ.) and has a
hysteresis width of 25(typ.). When IC chip temperature rises and TSD circuit works, the output terminal becomes an
open state. TSD circuit is designed only to shut the IC off to prevent thermal runaway. It is not designed to protect the
IC or guarantee its operation. Do not continue to use the IC after operation this circuit or use the IC in an environment
where the operation of this circuit is assumed.
10) Testing on application boards
When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to
stress. Always discharge capacitors after each process or step. Always turn the IC’s power supply off before
connecting it to or removing it from a jig or fixture during the inspection process. Ground the IC during assembly steps
as an antistatic measure. Use similar precaution when transporting or storing the IC.
11) GND wiring pattern
When using both small signal and large current GND patterns, it is recommended to isolate the two ground patterns,
placing a single ground point at the ground potential of application so that the pattern wiring resistance and voltage
variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to
change the GND wiring pattern of any external components, either.
12) Capacitor between output and GND
When a large capacitor is connected between output and GND, if Vcc is shorted with 0V or GND for some cause, it is
possible that the current charged in the capacitor may flow into the output resulting in destruction. Keep the capacitor
between output and GND below 100uF.
13) IC terminal input
When Vcc voltage is not applied to IC, do not apply voltage to each input terminal. When voltage above Vcc or below
GND is applied to the input terminal, parasitic element is actuated due to the structure of IC. Operation of parasitic
element causes mutual interference between circuits, resulting in malfunction as well as destruction in the last. Do not
use in a manner where parasitic element is actuated.
14) In use
We are sure that the example of application circuit is preferable, but please check the character further more in
application to a part which requires high precision. In using the unit with external circuit constant changed, consider
the variation of externally equipped parts and our IC including not only static character but also transient character
and allow sufficient margin in determining
