General Description
The BH6578FVM and BD7931F are reversible motor
drivers with a wide output dynamic range, with power
MOS used for the output transistor. The motor drivers
can be set to four output modes 1) forward (normal)
rotation, 2) reverse rotation, 3) stop (idling or OFF)
and 4) brake using 2 logic inputs.
