short-circuiting between outputs, air contamination faults, or faults due to improper grounding, or by
short-circuiting between contiguous pins.
Vcc15 and VB may be turned on in either order. In turning off the power, take care not to cut off the VB line by
relay while the motor is spinning. Doing so may cause the IC to break down by cutting the current-producing route

Utmost care is necessary in the design of the output, V
In turning on the power, first supply Vcc15 and confirm its stability; then apply Vcc7 and the driving input signal.
The TB6581H/HG is sensitive to electrostatic discharge. Handle with care.
The product should be mounted by the solder-flow method. The preheating time is from 60 to 120 seconds at
