By Technology
AMIS30543 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 接口与外部微处理器进行联接。它具有片上稳压器、重置输出和监督重置,能够为外部器件供电。AMIS30543 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。该芯片提供了一个速度和负载角度输出。因此可以基于负载角度产生失速检测算法和控制回路,来调节转矩和速度。它使用专属的 PWM 算法实现可靠的电流控制。AMIS30543 在 I2T100 工艺中实施,在同一个芯片上可以同时实现模拟电路和数字功能。该芯片可完全兼容汽车电压要求。

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.)
