Motor driving chip and motor driving device

The invention provides a motor driving chip and device, and relates to the technical field of control, and the motor driving chip comprises a signal input port, a decoder, a driver and a driving signal output port. The signal input port is used for receiving a serial data signal from the data signal output end of the microcontroller based on a clock signal output by the clock signal output end of the microcontroller, and providing the received serial data signal to the decoder; the decoder extracts address data from an address field of the serial data signal, compares an address bit of the driving chip with the address data, extracts functional data from a functional field of the serial data signal when the address bit is the same as the address data, and provides the functional data to the driver; and the driver sends a driving signal to the at least one motor through the driving signal output port based on the function data so as to drive the at least one motor to work.
