Operating Description
· PWM control function
Speed can be controlled by inputting the high-level or low-level PWM signal to the pin PWM.
When PWM control is provided, normal operation and short brake operation are repeated.
To prevent penetrating current, dead time t2 and t4 is provided in the IC.

Note 1: The power supply capacitor should be connected as close as possible to the IC.
Note 2: When connecting the motor pins through the capacitor for reducing noise, connect a resistor to the capacitor
for limiting the charge current.

Requests Concerning Use of QON
Outline Drawing of Package
(Upper surface) (Lower surface)
When using QON, please take into account the following items.
Caution
(1) Do not carry out soldering on the island section in the four corners of the package (the section shown
on the lower surface drawing with diagonal lines) with the aim of increasing mechanical strength.
(2) The island section exposed on the package surface (the section shown on the upper surface drawing
with diagonal lines) must be used as (Note 6) below while electrically insulated from outside.
TB6552FN/FL
Note 6: Ensure that the island section (the section shown on the lower surface drawing with diagonal
lines) does not come into contact with solder from through-holes on the board layout.
· When mounting or soldering, take care to ensure that neither static electricity nor electrical
overstress is applied to the IC (measures to prevent anti-static, leaks, etc.).
· When incorporating into a set, adopt a set design that does not apply voltage directly to the island
section.
