FAN3268 双 2A 门极驱动器适用于在以最高 18 V 的电压轨运行的电机控制应用中驱动高压侧 P 沟道 MOSFET 和低压侧 N 沟道 MOSFET。该驱动器具有 TTL 输入阈值,提供从逻辑输入的缓冲和电平转换功能。内部电路提供欠电压锁闭功能,可在 VDD 电源电压低于运行水平时阻止输出开关设备运行。内部 100kΩ 电阻会将非反向输出低电平和反向输出偏置到 VDD,以便在启动间隔期间,逻辑控制信号不存在时保持外部 MOSFET 的关断状态。FAN3268 驱动器集成了用于最终输出级的 MillerDrive™ 结构。此双极 MOSFET 组合在 MOSFET 打开/关闭过程的米勒平坦区阶段提供高电流,可最大程度降低开关损耗,同时可提供轨对轨电压摆幅和逆向电流功能。FAN3268 具有两个独立的启用引脚,如果未联接则默认为导通状态。如果用于非反向沟道 A 的启用引脚拉低,OUTA 则强制为低电平;如果用于反向沟道 B 的启用引脚拉低,OUTB 则强制为高电平。如果一个输入保持未联接,内部电阻则会偏置多个输入,以便外部 MOSFET 为关断状态。

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.)
