Data Sheet REVERSIBLE MOTOR DRIVER General Description
The AZ6208B is a monolithic integrated circuit used for driving reversible motors. It can control rever-sible motors in cassette players and other electrical equipment by using TTL-level logic signals. The IC contains 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 (Typ.) according to the logic control. The AZ6208B is available in SIP-9 and SOIC-8 Package.
AZ6208B Features
* * * * * * Built-in Motor Driving Power Transistors (Typ. 100mA) Brake is Applied When Stopping the Motor (When Input A and B are Both HIGH Level) Built-in Diode to Absorb Surge Currents Very Low Standby Circuit Current When Input A and B are Both LOW Level Wide Range of Operating Supply Voltage (4.5 to 15.0V) Direct Control with the TTL Logic

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods may affect device reliability. Note 2: Power dissipation is reduced by 7 mW for each increase in TA of 1oC over 25oC. Note 3: Only apply for SOIC-8 package.
