TB6615PG
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TB6615PG
STEPPING MOTOR CONTROLLER / DRIVER
The TB6615PG is a stepping motor controller/driver with MOS output transistors.
The TB6615PG can drive a two-phase stepping motor in unipolar
mode, and allow the selection of rotation direction between
forward and reverse by using clock signals. It also supports
several excitation modes (1-phase, 2-phase and 1-2-phase).
FEATURES
z Single-chip stepping motor controller/driver
z All inputs are TTL level.
z The CK1, CK2, CW/CCW and RESET pins are Schmitt
trigger inputs.
z Rotation direction control (Clockwise (CW)/counterclockwise
(CCW)): Single-clock and dual-clock modes
Weight : 1.11 g (typ.)
z Output enable and initial state detection capabilities
z High output withstand voltage: VCE (SUS)φ = 28 V (MIN)
z High output current: IOUTφ = 400 mA (MAX)
z Package: DIP-16
z The overvoltage protection circuitry is provided on each output. (It is activated when the output voltage
reaches 30 V (typ.) or higher.)

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.
