概览

NCV7703B 是一款全保护型三半桥驱动器，特别适用于汽车和工业运动控制应用。三个半桥驱动器具有独立控制。 因此可实现高压侧、低压侧和 H 桥控制。H 桥控制提供正向、逆向、制动和高阻抗状态。 驱动器通过标准 SPI（串行外围接口）进行控制。该器件完全兼容安森美半导体的 NCV7708B 双六路驱动器。

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.)
