Typical Application Examples
Note 1: A bypass capacitor should be connected between V
CC
and P-GND and placed as close as possible to the
TB6559FG.
Note 2: When a capacitor is connected between the motor pins to reduce noise, a resistor should also be inserted to
limit the charge current. This capacitor causes the switching loss to increase for PWM control; therefore, this
capacitor should not be used, if possible.
Note 3: S-GND and P-GND should be short-circuited at a location as close to the TB6559FG as possible. (Same for
Fin)
Note 4: The capacitor C
1
should be connected to S-GND.
Note 5: If there is chattering or noise in the output signal, connect an RC filter to ALERT.

Usage Precautions
• Although the TB6559FG contains overcurrent detection circuitry, a large current might abruptly flow through
the IC in case of a short-circuit to power supply, a short-circuit to ground or a short-circuit across the load,
damaging the device permanently. This possibility should be fully considered in the design of the output, V
CC
and ground lines. If the device is damaged, a large current might continually flow through the device as a
secondary effect. Therefore, Toshiba recommends that a fuse be connected to the power supply line.
• Install this IC properly. If not, (e.g., installing it in the wrong position), the IC might be broken.
• If external components are shorted together, the IC might be broken.
