UNISONIC TECHNOLOGIES CO., LTD BA6208 LINEAR INTEGRATED CIRCUIT REVERSIBLE MOTOR DRIVER DIP-8 DESCRIPTION The UTC 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. SIP-9 FEATURES * Recommended operating supply voltage range from 4.5V to15.0V. * Built-in motor driving power transistors(typ.100mA). * Brake is applied when stopping the motor (when Ain and Bin are both HIGH level). * Very low standby circuit current(when Ain and Bin are both LOW level. * Built-in diode to absorb surge currents. * Direct control with the TTL logic.
