AN6663S

AN6663S, AN6663SP Bridge Drivers s Overview The AN6663S and AN6663SP are the forward/reverse drive ICs for small DC motors. They provide 4 Kinds of outputs such as foward rotation, reverse rotation, brake, and stop by the 2bit input and are optimum as the drivers for the small motors of 100 to 150mA.
