Reversible Motor Drivers for Brush Motors 1.0A or More Reversible Motor Drivers (2 Motors) No.11008EBT04 BA6247FP-Y, BA6238A 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 ouput t 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) Ratings Parameter Symbol Unit BA6247FP-Y BA6238A Supply voltage VCC1, VCC2 20 20 V 1 1 Output current I 1* 1.6* A OMAX Control input pins V -0.2 ~ 6.0 -0.3 ~ 5.0 V IN Operating temperature T -25 ~ 75 -25 ~ 75 OPR Storage temperature T -55 ~ 150 -55 ~ 125 STG 4 2 3 Power dissipation Pd 1.45* / 0.95*2.0* W Junction temperature T 150 125 jmax *1 Do not, exceed Pd or ASO (Pulse at 1/50 duty: 50ms). *2 HSIP10 package.
