TB6552FNG/FTG
Toshiba Bi-CD Integrated Circuit Silicon Monolithic
TB6552FNG, TB6552FTG
DUAL-BRIDGE DRIVER IC FOR DC MOTORS
The TB6552FNG/FTG is a dual-bridge driver IC for DC motors
with output transistors in an LD MOS
structure with low ON-resistance. Two input signals, IN1 and
IN2, can choose one of four modes such as CW, CCW, short brake,
and stop mode. A PWM drive system supports high heat
efficiency driving.
Features
• Power supply voltage for motor: VM ≤ 15 V (max)
• Power supply voltage for control: VCC = 2.7 V to 6.0 V
• Output current: 1 A (max)
• Low ON resistor: 1.5 Ω (typ.)
(Upper side + lower side combined @ VM = 5 V)
• Direct PWM control
• Standby system (power saving)
• CW/CCW/short brake/stop function modes
• Built-in thermal shutdown circuit
• Package: FNG-SSOP16/FTG-WQFN16

* This product has a MOS structure and is sensitive to electrostatic discharge. When handling this product,
ensure that the environment is protected against electrostatic discharge by using an earth strap, a conductive
mat and an ionizer. Ensure also that the ambient temperature and relative humidity are maintained at
reasonable levels.

IC Usage Considerations
Notes on handling of ICs
[1] The absolute maximum ratings of a semiconductor device are a set of ratings that must not be
exceeded, even for a moment. Do not exceed any of these ratings.
Exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result
injury by explosion or combustion.
[2] Use an appropriate power supply fuse to ensure that a large current does not continuously flow in
case of over current and/or IC failure. The IC will fully break down when used under conditions that
exceed its absolute maximum ratings, when the wiring is routed improperly or when an abnormal
pulse noise occurs from the wiring or load, causing a large current to continuously flow and the
breakdown can lead smoke or ignition. To minimize the effects of the flow of a large current in case
of breakdown, appropriate settings, such as fuse capacity, fusing time and insertion circuit location,
are required.
[3] If your design includes an inductive load such as a motor coil, incorporate a protection circuit into
the design to prevent device malfunction or breakdown caused by the current resulting from the
inrush current at power ON or the negative current resulting from the back electromotive force at
power OFF. IC breakdown may cause injury, smoke or ignition.
Use a stable power supply with ICs with built-in protection functions. If the power supply is
unstable, the protection function may not operate, causing IC breakdown. IC breakdown may cause
injury, smoke or ignition.
[4] Do not insert devices in the wrong orientation or incorrectly.
Make sure that the positive and negative terminals of power supplies are connected properly.
Otherwise, the current or power consumption may exceed the absolute maximum rating, and
exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result
injury by explosion or combustion.
In addition, do not use any device that is applied the current with inserting in the wrong orientation
or incorrectly even just one time.
