Reversible Motor Drivers for Brush Motors 2.0A or More Reversible Motor Drivers (Single Motor) BA6219BFP-Y,BA6222 No.11008EBT03 Description These motor drivers are full bridge drivers for brush motor applications, supporting output currents of up to 2A. The output modes are available in four modes, normal, reverse, stop (idling), and braking in accordance with input logic (2 inputs). The output voltage can be optionally set by reference voltage setting pin. Features 1) Large output current (l =2.2A) OMAX 2) Built-in thermal shutdown circuit 3) Output voltage can be optionally set by reference voltage setting pin 4) High output voltage can be set by low voltage input because of it has 11.4dB gain (BA6222) 5) Low standby current 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 BA6219BFP-Y BA6222 Supply voltage VCC1, VCC2 24 V 1 Output current I 2.2* A OMAX All other input pins V -0.3 ~ VCC1 -0.3 ~ VCC1+0.3 V IN Operating temperature T -25 ~ 75 OPR Storage temperature T -55 ~ 150 -55 ~ 125 STG 2 3 Power dissipation Pd 1.45* 2.00* W Junction temperature T 150 125 jmax *1 Do not, exceed Pd or ASO (Pulse at 1/100 duty: 500s). *2 HSOP25 package.
