3. Lock protection function
If hall input signal is stop, the lock protection circuit is determined that detection of lock protection. When the lock
protection circuit is detect lock protection, all predriver output is fix to Low.
Terminal CT1 capacitor and lock protection ON time (TON1)
TON1(Charging time)=(VLOCKP_H- VLOCKP_L) / (ILOCK/C)
C : CT1 Capacity of terminal external capacitor
ILOCK : SOURCE current for lock protection detection (TYP.:1µA)
VLOCKP_H : Terminal CT1 comparison H voltage (TYP.:3.85V)
VLOCKP_L : Terminal CT1 comparison L voltage (TYP.:0.55V)
Reference value (example)
At CT1=1µF
TON1=(3.85-0.55)V / (1µA/1µF)=3.3s
At CT1=10µF
TON1=(3.85-0.55)V / (1µA/10µF)=33s
Our company is recommending the range of 0.1µF-10µF to the capacitor of CT1.
CT1 is shorted to GND when the lock protection time is not set.

When the lock protection is released and it reactivates, the CT1 capacitor should be completely discharged.
Discharge SW of Figure-3 is turned on to integral value 47.7% as shown in Figure-7, 8. Please raise PWM input DUTY
after discharging the CT1 capacitor.
(Reference)
The discharge time is decided by the expression of ΔV=(1-e-t / (C x R) ) x ΔV(initial value).
At t= C x R, it becomes the standing fall time of 63.2%.
ON resistance of SW for CT1 discharge becomes MAX.=320Ω.
(Refer to electric characteristic CT1 terminal item P.6.)
4. Over power supply voltage output OFF function
Over power supply voltage output OFF function is built into as output protection at the over voltage. When the impressed
voltage to the terminal VCC becomes 30V (TYP.) or more, all Predriver output terminal becomes Low. However, it is only
STB=Hi as the operation condition. Please note that this function doesn't operate because the current supply also stop in IC
at STB=Low (At the standby).
Over power supply voltage output OFF function is built into. Please do not exceed the absolute maximum rating so that
there is a possibility of destruction when the absolute maximum rating of the power supply voltage is exceeded.

●Operational Notes
1) We are careful enough for quality control about this IC. So, there is no problem under normal operation, excluding that
it exceeds the absolute maximum ratings. However, this IC might be destroyed when the absolute maximum ratings,
such as impressed voltages (VCC) or the operating temperature range,
is exceeded, and whether the destruction is short circuit mode or open circuit mode cannot be specified. Please take
into consideration the physical countermeasures for safety, such as fusing, if a particular mode that exceeds the
absolute maximum rating is assumed.
2) GND line
The ground line is where the lowest potential and transient voltages are connected to the IC.
3) Input terminal
Please do not add the voltage to each input terminal when you do not impress VCC to IC.
4) BEMF
BEMF might be changed depending on use conditions and an individual characteristic of the environment
and the motor. Please confirm there is no problem in the operation of IC by BEMF.
5) VCC
Please put coupling capacitor 10μF or more in the power supply between the power supply and GND.
6) Power dissipation
Power dissipation is changed by the state of the substrate mounting and the mounting environment of IC,
and take care enough about the heat design.
7) Power consumption
Power consumption changes greatly depending on the power-supply voltage and the output current. Please design
heat after considering the thermal resistance data and the transition thermal resistance data, etc. to consider power
dissipation, and so as not to exceed ratings.
8) ASO
Please set not to exceed ASO (area of safe operation) the output current and the power-supply voltage.
9) The circuit that limits the inrush current is not built into this IC. Therefore, please consider physical measures of putting
the current limitation resistance.
10) There is a possibility that the trouble of the malfunction occurs if the potential of the output terminal widely swings to
the potential of GND or less in this IC according to conditions such as the generation of heat condition, power-supply
voltages, and the use motors. For that case, please consider measures where trouble doesn't occur as shot key
diode is added between GND-output.
11) Radiation
This IC doesn't do the design that assumes use in strong electromagnetic field. Please confirm there is no problem in
the operation of IC by the substrate pattern layout and the circuit constant enough.
12) Thermal shutdown
The thermal shutdown circuit is built into as an overheating protection measures this IC. When the Chip temperature
of IC becomes 175°C (TYP.) or more, the output is opened. It returns to normal operation when becoming
150°C (TYP.) or less.
13) FG output signal
When the noise is generated in the hall signal, the FG signal might do chattering. Especially, the possibility that
chattering is caused as the power-supply voltage touches rises when rapidly changing from the normal rotation into
the reversal rotation or from the reversal rotation into the normal rotation. CAPA is inserted between the hall input
terminals to decrease the noise of the hall signal, and the attention such as enlarging the input level is necessary
when using it like this.

14) Wrong direction assembly of the device.
Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any
connection error.
15) Regarding input pin of the IC l
This monolithic IC contains P+ isolation and P substrate layers between adjacent elements to keep them isolated.
PN junctions are formed at the intersection of these P layers with the N layers of other elements, creating a parasitic
diode or transistor. For example, the relation between each potential is as follows:
When GND > Pin A and GND > Pin B, the PN junction operates as a parasitic diode.
When Pin B > GND > Pin A, the PN junction operates as a parasitic transistor.
Parasitic diodes can occur inevitably in the structure of the IC. The operation of parasitic diodes can result in mutual
interference among circuits, operational faults, or physical damage. Accordingly, methods by which parasitic diodes
operate, such as applying a voltage that is lower than the GND (P substrate) voltage to an input pin, should not be
used
