    產(chǎn)品信息

    The NCV70514 is a micro?stepping stepper motor driver for bipolar stepper motors. The chip is connected through I/O pins and an SPI interface with an external microcontroller. The NCV70514 contains a current?translation table and takes the next micro?step depending on the clock signal on the “NXT” input pin and the status of the “DIR” (= direction) register or input pin. The chip provides an error message if stall, an electrical error, an under?voltage or an elevated junctiontemperature is detected. It is using a proprietary PWM algorithm for reliable current control.NCV70514 is fully compatible with the automotive voltage requirements and is ideally suited for general?purpose stepper motor applications in the automotive, industrial, medical, and marine environment.Due to the technology, the device is especially suited for use in applications with fluctuating battery supplies.
