FAN3180 将高速低端栅极驱动器与 3.3V 输出低压差稳压器(LDO)相结合。栅极驱动器在 VDD 电压为 12V 时的额定电流为 2.8A 峰值电流,设计用于在低端开关应用驱动一个 N 沟道增强型 MOSFET产品。FAN3180 还集成了 3.3V ,15mA 的低压差稳压器、在25°C 时的 ±1% 严格电压容差及为外部微控制器供电的 ±2.5% 总变化。
内部电路提供了欠压锁定(UVLO)功能,方法为将输出保持在低电平,直到电源电压在工作范围之内且检测到第一个全输入脉冲。FAN3180 有4.75 V VON 和4.55 V VOFF 的欠压锁定 UVLO 阈值,最大待机电流为 200µA。
该驱动器提供了快速MOSFET开关性能,以最大化高频电源转换器的效率。它采用了 MillerDrive™ 架构,以便用于最终输出驱动级。这一双极性器件/MOSFET组合可在MOSFET导通/关断过程的Miller平台期间提供高峰值电流,以最大限度减少开关损耗,同时提供轨到轨电压摆幅和反向电流能力。包括热关断功能,作为一个附加的安全功能。

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.)
