Reversible Motor Drivers for Brush Motors
1.0A Reversible
Motor Drivers (Single Motor)
BA6956AN,BA6287F,BA6285FS,BA6285AFP-Y,BA6920FP-Y
No.11008EBT02
●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)
