Typical Application Examples
Note 1: A bypass capacitor should be connected between V
Note 2: When a capacitor is connected between the motor pins to reduce noise, a resistor should also be inserted to
Note 3: S-GND and P-GND should be short-circuited at a location as close to the TB6559FG as possible. (Same for
Note 4: The capacitor C
Note 5: If there is chattering or noise in the output signal, connect an RC filter to ALERT.

limit the charge current. This capacitor causes the switching loss to increase for PWM control; therefore, this
capacitor should not be used, if possible.
