概览

NCV70517 是一款用于双极步进电机的微步进电机驱动器。该芯片通过 IO 引脚和 SPI 接口与外部微控制器进行联接。NCV70517 包含一个电流转换表，根据 NXT 输入引脚上的时钟信号以及 DIR（方向）寄存器或输入引脚的状态采用下一个微步进。如果检测到电气错误、欠电压或结温升高，该芯片则会提供错误消息。它使用专属的 PWM 算法实现可靠的电流控制。 NCV70517 完全符合汽车电压要求，非常适合汽车、工业、医疗和海洋环境中的通用型步进电机应用。 由于采用这一技术，此器件特别适合使用波动电池电源的应用。

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
