Reversible Motor Drivers for Brush Motors
1.0A or More Reversible
Motor Drivers (2 Motors)
BA6247FP-Y, BA6238A
No.11008EBT04
●Description
The reversible motor driver for output 1.0A or more for two motors drives a brush motor and incorporates one and a half
circuits of reversible motor driver. In addition, since the output section can control voltage applied to motors by output high
voltage setting pin, the torque at the time of driving motors can be varied.
●Features
1) Built-in one and a half circuits of a reversible motor driver
2) Minimal external components
3) Output voltage can be optionally set by reference voltage setting pin
4) Built-in thermal shutdown circuit
●Applications
Audio-visual equipment; PC peripherals; Car audios; Car navigation systems; OA equipments
●Absolute maximum ratings (Ta=25℃, All voltages are with respect to ground)
