TECHNICAL NOTE
Reversible Motor Driver IC Series for Brush Motors
Reversible Motor Driver
for Output 1.0Aormore 2 Motors
BA6246/N,BA6247FP-Y,BA6239A,BA6238A/AN
●Description
The reversible motor driver for output 1.0A or more for 2 motors drives a brush type DC motor and incorporates one and a
half circuits of reversible motor driver. A logic input section necessary for controlling each motor can be easily connected to
the control logic such as CMOS, etc. In addition, since the output section can control voltage applied to motors by output
High voltage setting terminal (VR) voltage, the torque at the time of driving motors can be varied.
●Features
1) Built-in one and a half circuits of a reversible motor driver
2) Minimal external parts
3) Input can be directly connected to CMOS (however, when CMOS output is 5V or more, protection resistor is required).
4) Built-in power transistor for motor driver
5) Built-in thermal shutdown circuit
6) Output voltage can be optionally set by output High voltage setting terminal.
●Applications
VTR, tape deck, audio equipment in general, OA equipment in general

1) Input conditions
The motor output varies in accord with the input logic table (P5, 6).
VREG≒5V(BA6246/N, BA6247FP-T)

(2) The input terminal is pulled up at about 15 k Ω (see Fig. 22).
In order to secure the input level, set the interface with current sink
capability of not less than 700 μA (5V/15kx2).

(3) The maximum input voltage is 6V (BA6246/N, BA6247FP-Y) and
5V (BA6238A/AN, BA6239A), respectively.
7.5kΩ

Set input voltage with care not to exceed the maximum input voltage.
2) Output voltage control
Fig.22
Output H voltage can be set by VR terminal applied voltage. By varying the output H voltage, motor speed can be
adjusted.
In the case of BA6246/N, BA6247FP-Y, and BA6338A/AN:
The circuit configuration of each output terminal and VR terminal is shown as per the illustration on the right (Fig. 23).
From the VR terminal, constant current determined inside IC:
IVR=IC-IB≒IC
flows out.
Output H voltage is expressed by:
VOH[V]=VR+{VF(Q4)+VF(Q5)-VF(Q2)-VF(Q3)}
≒VR
VR：VR terminal applied voltage
VF：0.75V [reference value]
For output voltage VOL, see reference data (3/8).

In addition, the VR voltage range to which output H voltage setting is enabled is;
０＜VR＜VCC1-Vsat(Q1)- VF(Q4)-VF(Q5) ≒VCC1-1.7V

０＜VR＜VCC2-Vsat(Q3)+ VF(Q3)+VF(Q2)-VF(Q4)-VF(Q5) ≒VCC2-0.1V

OUT
Fig.23
(BA6239A)
The circuit configuration of each output terminal and VR terminal is shown as per the illustration on the right (Fig. 24).
Output H voltage is expressed by:
VOH=VR-Vsat(Q1)-VF(Q2)
To the VR terminal, connect the power supply that can supply current according to the output current.
In addition, set VR terminal voltage not to exceed voltage of VCC1 terminal and VCC2 terminal.
3) Change-over of normal rotation to and from reverse rotation
When the motor rotating method is changed over with the motor rotated, allow the motor to temporarily go through the
brake-applied condition or the open condition.
The duration of brake mode should be:
more than braking time when the mode is switched from rotation to braking：
(Braking time is defined as the time when the output L terminal becomes the potential lower than GND with
brake applied.)
The duration of open mode should be 1 msec or more.
●
Cautions on use
1) Absolute Maximum Ratings
For the present product, thoroughgoing quality control is carried out, but in the event that applied voltage, working temperature
range, and other absolute maximum rating are exceeded, the present product may be destroyed. Because it is unable to identify
the short mode, open mode, etc., if any special mode is assumed, which exceeds the absolute maximum rating, physical safety
measures are requested to be taken, such as fuses, etc.
2) Reverse connection of power supply connector
Reverse connection of power supply connector may destroy the IC. Take necessary measures to protect the IC from reverse
connection breakage such as externally inserting diodes across power supply and IC power supply terminal as well as across
power supply and motor coil.
3) Power supply line
Because return of current regenerated by Back-EMF of a motor occurs, take necessary measures such as inserting capacitors
across the power supply and GND as a path for regenerated current, and determine the capacity value after thoroughly confirming
that there would be no problems in various characteristics such as capacitance drop at low temperature which may occur with
electrolytic capacitors. By the way, in the event that the power supply connected does not have sufficient current absorbing
capability, voltage of the power supply line rises due to regenerative current and there is a fear in that the present product
including the peripheral circuits exceeds the absolute maximum rating. It is therefore requested to provide physical safety
measures, such as inserting a diode for voltage clamp across power supply and GND, etc.
4) Electrical potential at GND
Keep the GND terminal potential to the minimum potential under any operating condition. In addition, check if there is actually any
terminal, which provides voltage below GND including transient phenomena.
5) Thermal design
Consider the power dissipation (Pd) under actual working condition and carry out thermal design with sufficient margin provided.
6) Short-circuiting between terminals, and mismounting
When mounting to PCB, care must be taken to avoid mistake in its orientation and alignment. Failure to do so may result in IC
breakdown. Short-circuiting due to foreign matters entered between output terminals, or between output and power supply or
GND may also cause breakdown.
7) Operation in strong electromagnetic field
The use in the strong electromagnetic field may sometimes cause malfunction, to which care must be taken.
8) ASO
When IC is used, design in such a manner that the output transistor does not exceed absolute maximum ratings and ASO.
9) Built-in thermal shutdown circuit
The thermal shutdown circuit is first and foremost intended for interrupt IC from thermal runaway, and is not intended to protect and
warrant the IC. Consequently, never attempt to continuously use the IC after this circuit is activated or to use the circuit with the
activation of the circuit premised.
6/8
10)Capacitor across output and GND
In the event a large capacitor is connected across output and GND, when VCC and VIN are short-circuited with 0V or GND for some
kind of reasons, current charged in the capacitor flows into the output and may destroy the IC. Use a capacitor smaller than 1 μF
between output and GND.
11) Inspection by set substrate
In the event a capacitor is connected to a pin with low impedance at the time of inspection with a set substrate, there is a fear of
applying stress to the IC. Therefore, be sure to discharge electricity for every process. Furthermore, when the set substrate is
connected to a jig in the inspection process, be sure to turn OFF power supply to connect the jig and be sure to turn OFF power
supply to remove the jig. As electrostatic measures, provide grounding in the assembly process, and take utmost care in
transportation and storage.
12) IC terminal input
The present IC is a monolithic IC and has P+ isolation and a P substrate between elements to separate elements. With this P layer
and N layer of each element, PN junction is formed, and various parasitic elements are formed. For example, when resistors and
transistors are connected to terminals as is the case of Fig. 24, where in the case of resistor, the potential difference satisfies the
relation of ground (GND)>(terminal A), and in the case of transistor (NPN), the potential difference satisfies the relation of ground
(GND)>(terminal B), PN junction works as a diode. Furthermore, in the case of transistor (NPN), a parasitic NPN transistor
operates by the N-layer of other elements adjacent to the parasitic diode. The parasitic element is inevitably formed because of the
IC construction. The operation of the parasitic element gives rise to mutual interference between circuits and results in malfunction,
and eventually, breakdown. Consequently, take utmost care not to use the IC to operate the parasitic element such as applying
voltage lower than GND (P substrate) to the input terminal. In addition, when the power supply voltage is not applied to IC, do not
apply voltage to the input terminal, either. Similarly, when the power supply voltage is applied, each input terminals shall be the
voltage below the power supply voltage or within the guaranteed values of electrical properties.

13) GND wiring pattern
If there are a small signal GND and a high current GND, it is recommended to separate the patterns for the high current GND and
the small signal GND and provide a proper grounding to the reference point of the set not to affect the voltage at the small signal
GND with the change in voltage due to resistance component of pattern wiring and high current. Also for GND wiring pattern of the
component externally connected, pay special attention not to cause undesirable change to it.
