Abstract
A motor driving device includes a microcomputer, a command voltage adjusting circuit, and a driving IC. The command voltage adjusting circuit converts a first command voltage signal from the microcomputer to a second command voltage signal. The driving IC generates a drive pulse based on the second command voltage signal. An upper and a lower limit of an input voltage range of the driving IC are larger than an upper and a lower limit of a voltage range of the first command voltage signal, respectively.
