UTCBA6208 LINEAR INTEGRATED CIRCUIT
REVERSIBLE MOTOR DRIVER
DESCRIPTION
The UTC BA6208 is 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.
FEATURES
*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.
*Very low standby circuit current when inputs A and B are
both LOW level.
*Wide range of operating supply voltage (4.5 ~ 15.0V)
*Direct control with the TTL logic.
