NV705223R1DBGEVB: Daughterboard SPI Stepper Driver with

Voltage Regulator (NQFP) Evaluation Board

Evaluation Board Description

The NV705223R1DBGEVB is a form factor

Reference Design for driving bipolar stepper

motors. The reference design can be

interfaced via I/O pins and the SPI bus to an

external microcontroller. In conjunction with

the NCV7052xGEVK evaluation kit it forms a

complete solution turning high level

commands from a CAN node in well defined

motions. The design incorporates the lowest

bill of materials, small board size and perfect

matched thermal resistance allowing to drive

800 mA at elevated ambient temperature or

even 1.6A under certain conditions.

Note: This board must be used with the

NCV7052XGEVK Automotive Stepper Motor

Driver Kit.
