BA6208 Motor Driver

BA6208 is designed for driving reversible motor use, it contain a logic section to controls forward and reverse rotations as well as forced stop, and an output power section is able to supply an output current of up to 100mA (typical) according to the logic control. The IC allow control of reversible motors in cassette players and other electrical equipment by using TTL-level logic signals.
