Reversible Motor Drivers for Brush Motors 1.0A Reversible Motor Drivers (Single Motor) No.11008EBT02 BA6956AN,BA6287F,BA6285FS,BA6285AFP-Y,BA6920FP-Y Description The reversible motor driver for output 1.0A for 1 motor can set the output modes to four modes, normal, reverse, stop (idling), and braking in accordance with logic input (2 inputs). Features 1) Built-in surge absorption diode 2) By built-in power save circuit, current consumption when a motor stops (idles) can be suppressed 3) Output voltage can be optionally set by reference voltage setting pin 4) Built-in thermal shutdown circuit (TSD) 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 BA6956AN BA6287F BA6285FSBA6285AFP-Y BA6920FP-Y Supply voltage VCC 18 18 18 30 36 V Supply voltage VM 18 18 18 30 36 V 1 1 1 1 1 Output current I 1* 1* 1* 1* 1* A OMAX Operating temperature T -20 ~ 75 -20 ~ 75 -20 ~ 75 -40 ~ 85 -30 ~ 85 OPR Storage temperature T -55 ~ 150 -55 ~ 150 -55 ~ 150 -55 ~ 150 -55 ~ 150 STG 2 3 4 5 5 Power dissipation Pd 1.19* 0.689* 0.813* 1.45* 1.45* W Junction temperature T 150 150 150 150 150 jmax *1 Do not, exceed Pd or ASO. *2 SIP9 package.
