TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA7267BP
Full-Bridge Driver (H-Swithch) for DC Motor
(Driver for Switching between Forward and Reverse Rotation)
TA7267BP
The TA7267BP is a Bridge Driver for brushed DC Motor Rotation
control.
Forward Rotation, Reverse Rotation, Stop and Braking
operations are available.
It’s designed for Loading and Reel Motor driver for VCR and Tape
Deck, and any other consumer and industrial applications.
TA7267BP have Operation Supply Voltage terminal and Motor
Driving Supply Voltage terminal independently, therefore Servo
control operation is applicable.
Features
Weight: 2.15 g (typ.)
z Output current up to 1.0 A (AVE.), and 3.0 A (PEAK)
z Four different modes (forward rotation, reverse rotation, stop, and brake) are supported.
z Built-in overcurrent protection and thermal shutdown circuit
z Operating voltage range: VCC (opr.) = 6 to 18 V, VS (opr.) = 0 to 18 V
z No malfunction occurs even if VCC is higher than VS or Vice versa.
The TA7267BP is Sn plated product including Pb.
The following conditions apply to solderability:
*Solderability
1. Use of Sn-37Pb solder bath
*solder bath temperature = 230°C
*dipping time = 5 seconds
*number of times = once
*use of R-type flux
2. Use of Sn-3.0Ag-0.5Cu solder bath
*solder bath temperature = 245°C
*dipping time = 5 seconds
*the number of times = once
*use of R-type flux

application equipment.
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.
