TIGER ELECTRONIC CO.,LTD R EVERSIBLE MOTOR DRIVER B A 6208 /BA6208F D ESCRIPTION T he B A 6208 /BA6208BF a re monolithic ICs used for d riving reversible mo tors. They allow c ontrol of reversible motors in cassette p layers and other electrical equipment by u sing 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. O utline Drawing BA6208 SIP9 BA6208F F EATURE M otor driving power transistors are built in (100mA typically) B rake is applied when stopping the motor (when in-puts A and B are both HIGH level). B uilt-in diode to absorb surge currents. V ery low standby circuit current when inputs A and Bare both LOW level. W ide range of operating supply voltage (4.5~15.0V). D irect control with the TTL logic.
