For brush motors Reversible motor drivers (for two motors series) BA6246, BA6246N, BA6247FP-Y, BA6239A, BA6238A, BA6238AN Overview 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°C, All voltages are with respect to ground) Parameter Symbol Ratings Unit BA6246/N BA6247FP-Y BA6239A BA6238A/AN Supply voltage VCC1, VCC2 20 20 20 20 V Output current IOMAX 1* 1 1* 1 1.2* 2 1.6* 1 A Control input pins VIN -0.2 ~ 6.0 -0.2 ~ 6.0 -0.3 ~ 5.0 -0.3 ~ 5.0 V Operating temperature TOPR -25 ~ 75 -25 ~ 75 -25 ~ 75 -25 ~ 75 °C Storage temperature TSTG -55 ~ 150 -55 ~ 150 -55 ~ 125 -55 ~ 125 °C Power dissipation Pd 2.5* 3 / 1.19*4 1.45* 5 2.0* 3 2.0* 3 / 0.95*4 W Junction temperature Tjmax 150 150 125 125 °C *1 Do not, exceed Pd or ASO (Pulse at 1/50 duty: 50ms). *2 Do not, exceed Pd or ASO (Pulse at 1/100 duty: 500µs). *3 HSIP10 package.
