○Operation Notes
(1)
Absolute maximum ratings
Use of the IC in excess of absolute maximum ratings such as the applied voltage or operating temperature range (Topr) 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 lines
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.

(7)
Thermal shutdown circuit
Ensure a minimum GND pin potential in all operating conditions.
Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions.
Use caution when using the IC in the presence of a strong magnetic field as doing so may cause the IC to malfunction.
When using the IC, set the output transistor for the motor so that it does not exceed absolute maximum ratings or ASO.
This IC incorporates a TSD (thermal shutdown) circuit (TSD circuit). If the temperature of the chip reaches the following
temperature, the motor coil output will be opened. The thermal shutdown circuit (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.
