Reversible Motor Drivers with Speed Control - BA6951FS

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. Inaddition, since voltage applied to motors varies in accord with the control terminal, motor rotating speed can be optionallyset and by the built-in current feedback amplifier, the motor can be driven at a constant speed.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
