REVERSIBLE MOTOR DRIVER BA6208/BA6208F
ꢀ DESCRIPTION
Outline Drawing
The BA6208/BA6208BF 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.

FEATURE
ꢀ
Motor driving power transistors are
built in (100mA typically)
ꢀ
Brake is applied when stopping the motor
(when in-puts A and B are both HIGH level).
Built-in diode to absorb surge currents.
SOP8
ꢀ
ꢀ
ꢀ
ꢀ
Very low standby circuit current when inputs A and Bare both LOW level.
Wide range of operating supply voltage (4.5~15.0V).
Direct control with the TTL logic.
