(4) Power good filter function
Power good filter works when VP drops lower than 70%(typ.) of VP setting voltage, and the filer is reset when VP
voltage increase higher than 90%(typ.) of VP setting voltage. When VP drops lower than 70% and it takes longer than
5.3ms (typ.) to recover, Power Good signal turns from Hi to Lo.
* When PGFIL_=1’b0(default), power good filter is enabled, and when PGFIL_=1’b1, disabled.

when VP terminal voltage becomes under +10%(typ.) more than VP setting voltage, SWO switching restarts OVP function

●Operational Notes
1) Absolute maximum ratings
Use of the IC in excess of absolute maximum ratings such as the applied voltage or operating temperature range may
result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode) when
such damage is suffered. The implementation of a physical safety measure such as a fuse should be considered when
use of the IC in a special mode where the absolute maximum ratings may be exceeded is anticipated.
2)
Power supply pins and lines
None of the VP line for the H-bridges is internally connected to the VCC power supply line, which is only for the control
logic or analog circuit. Therefore, the VP and VCC lines can be driven at different voltages. Although these lines can be
connected to a common power supply, do not open the power supply pin but connect it to the power supply externally.
Regenerated current may flow as a result of the motor's back electromotive force. Insert capacitors between the power
supply and ground pins to serve as a route for regenerated current. Determine the capacitance in full consideration of
all the characteristics of the electrolytic capacitor, because the electrolytic capacitor may loose some capacitance at
low temperatures. If the connected power supply does not have sufficient current absorption capacity, regenerative
current will cause the voltage on the power supply line to rise, which combined with the product and its peripheral
circuitry may exceed the absolute maximum ratings. It is recommended to implement a physical safety measure such
as the insertion of a voltage clamp diode between the power supply and ground pins.
For this IC with several power supplies and a part consists of the CMOS block, it is possible that rush current may flow
instantaneously due to the internal powering sequence and delays, and to the unstable internal logic, respectively.
Therefore, give special consideration to power coupling capacitance, width of power and ground wirings, and routing of
wiring.
3)
Ground pins and lines
Ensure a minimum GND pin potential in all operating conditions. Make sure that no pins are at a voltage below the
GND at any time, regardless of whether it is a transient signal or not.
When using both small signal GND and large current PGND patterns, it is recommended to isolate the two ground
patterns, placing a single ground point at the application's reference point 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.
The power supply and ground lines must be as short and thick as possible to reduce line impedance.
4)
Thermal design
Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating
conditions.
5)
Actions in strong magnetic field
Use caution when using the IC in the presence of a strong magnetic field as doing so may cause the IC to malfunction.
6)
ASO
When using the IC, set the output transistor for the motor so that it does not exceed absolute maximum ratings or ASO.
7)
Thermal shutdown circuit
This IC incorporates a TSD (thermal shutdown) circuit. If the temperature of the chip reaches the following temperature,
the motor coil output will be opened. The TSD circuit is designed only to shut the IC off to prevent runaway thermal
operation. It is not designed to protect the IC or guarantee its operation. Do not continue to use the IC after operating
this circuit or use the IC in an environment where the operation of this circuit is assumed.
TSD ON temperature [°C] (Typ.)
Hysteresis temperature [°C] (Typ.)
175

8)
After releasing Under Voltage Locked Out (UVLO) or Thermal Shut Down (TSD)
When UVLO, TSD is released, it returns normal operation after 100µs (max).
9)
VBAT external power supply
This IC is not equipped with terminal of VBAT, and operate even the VBAT external power supply is lower than 4V
(minimum VP operation voltage). Give consideration that if VBAT external power supply is low and VP setting voltage is
high or load is large, may cause an overcurrent flowing through SWO terminal, and may enable OCP, TSD, etc. In
addition, if the VBAT external power supply has changed during the boost operation (ex. VBAT=HiZ), because of
boosting VP to setting voltage without working soft start / soft change, may cause overcurrent flowing through SWO
terminal. If VBAT external power supply is changing, stop boost operation by setting PS=0V or VPU=1’b0, then set the
soft start function after VBAT power supply voltage is stable.
10) N.C. pin
Always keep N.C. pin open.

The application circuit is recommended for use. Make sure to confirm the adequacy of the characteristics. When using
the circuit with changes to the external circuit constants, make sure to leave an adequate margin for external
components including static and transitional characteristics as well as dispersion of the IC.

safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which
a failure or malfunction of our Products may cause. The following are examples of safety measures:
[a] Installation of protection circuits or other protective devices to improve system safety
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
3.
Our Products are designed and manufactured for use under standard conditions and not under any special or
extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way
responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any
special or extraordinary environments or conditions. If you intend to use our Products under any special or
extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of
product performance, reliability, etc, prior to use, must be necessary:
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,

may be degraded. It is strongly recommended to confirm solderability before using Products of which storage time is
exceeding the recommended storage time period.
3.
Store / transport cartons in the correct direction, which is indicated on a carton with a symbol. Otherwise bent leads
may occur due to excessive stress applied when dropping of a carton.
