Application Circuit Example
Usage Considerations
Note: Capacitors for the power supply lines should be connected as close to the IC as possible.

A large current might abruptly flow through the IC in case of a short-circuit across its outputs, a short-circuit
to power supply or a short-circuit to ground, leading to a damage of the IC. Also, the IC or peripheral parts
may be permanently damaged or emit smoke or fire resulting in injury especially if a power supply pin
(V
or any other pins. These possibilities should be fully considered in the design of the output, V
ground lines.
A fuse should be connected to the power supply line. The rated maximum current of the TB6560AHQ is
3.5 A/phase and that of the TB6560AFG is 2.5 A/phase. Considering those maximum ratings, an
appropriate fuse must be selected depending on operating conditions of a motor to be used. Toshiba
recommends that a fast-blow fuse be used.
The power-on sequence described on page 28 must be properly followed.
