1.0A Reversible

Motor Drivers (Single Motor)

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)
