Reversible Motor drive IC Series for Brush Motors Reversible Motor Drivers for 0.8A or less (1 Motor) BA6950FS, BA6951FS Overview These drivers are reversible motor drivers that can directly drive brush motor which require forward and reverse rotations. Four modes of output setting are available by the use of input logic (2 inputs); forward, reverse, stop (idling), and braking. In addition, since voltage applied to motors varies in accord with the control terminal, motor rotating speed can be optionally set and by the built-in current feedback amplifier, the motor can be driven at a constant speed. Features 1) Four-mode outputs of forward, reverse, stop (idling), and braking are enabled in compliance with two inputs 2) Motors can be driven at a constant speed by a current feedback amplifier 3) Built-in thermal shutdown circuit 4) Built-in current limiting function (BA6951FS) 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 BA6950FS BA6951FS Supply voltage VCC 8 V Supply voltage VB 18 V Output current IOMAX 0.4* 1 0.8* 1 A Operating temperature TOPR -20 ~ 75 °C Storage temperature TSTG -55 ~ 150 °C Power dissipation Pd 0.813* 2 W Junction temperature Tjmax 150 °C *1 Do not, exceed Pd or ASO. *2 SSOP-A16 package. Mounted on a 70mm x 70mm x 1.6mm FR4 glass-epoxy board with less than 3% copper foil. Derated at 6.4mW/°C above 25°C.
