General Description
The AZ6208B is a monolithic integrated circuit used
for driving reversib le motors. It can control rever-sible
motors in cassette players and other electrical equip-
ment by using TTL-level logic signals.
The IC contains a logic section, which controls for-
ward 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 S IP-9 and SOIC-8 Pack -
age.
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 Wh en 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
Applications
·DVD Player

Power Dissipation PD 700 (Note 2, 3) mW
Storage Temperature Range TSTG -55 to 150 oC
Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" m ay cause perm anent dam age to the
device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indi-
cated 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.
