Motor driver ICs
Reversible motor driver
BA6208 / BA6208F
The BA6208 and BA6208F are monolithic ICs used for driving reversible motors. They allow control of reversible motors
in cassette players and other electrical equipment by using TTL-level logic signals.
The ICs contain a logic section, which controls forward and reverse rotations as well as forced stop, and an output power
section, which can supply an output current of up to 100mA (typical) according to the logic control.
F Features
1) Motor driving power transistors are built in (100mA
typically).
2) Brake is applied when stopping the motor (when in-
puts A and B are both HIGH level).
3) Built-in diode to absorb surge currents.
4) Very low standby circuit current when inputs A and B
are both LOW level.
5) Wide range of operating supply voltage (4.5
X
15.0V).
6) Direct control with the TTL logic.
