Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

半桥栅极驱动 IC
特性
说明
浮动通道可实现高达 +600V 的自举运行
FAN7384 是单片半桥栅极驱动 IC,设计用于高压、高速
驱动 MOSFET 和 IGBT,工作电压高达 +600V。
两个通道的源/灌电流驱动能力典型值为250mA/500mA
在 VDD= VBS= 15 V 时信号传播时,扩展允许的负 VS
飞兆半导体的高压工艺和共模噪声消除技术可以保证高侧
驱动器在高 dv/dt 噪声环境下稳定工作。
先进的电平转换电路使高侧栅极驱动器能承受高达
VS= -9.8V (典型值)的偏置电压,在 VBS=15V 时。
摆幅低达 -9.8 V
匹配传播延迟低于 50ns
输出信号与输入信号同相位
兼容 3.3V 和 5V 逻辑输入电平
内置直通预防逻辑
内置共模 dv/dt 噪声消除电路
两个通道均内置欠压锁定 (UVLO) 功能
内置逐周期关断功能
内置软关机功能
内置双向故障功能
内置短路保护功能
当 VDD 和 VBS 小于指定阈值电压时,欠压锁定 (UVLO) 电
路可防止发生故障。
输出驱动器的源电流 / 灌电流典型值分别为 250 mA/
500 mA,适用于电机驱动系统的半桥和全桥应用。

应力超过绝对最大额定值,可能会损坏器件。在超出推荐的工作条件的情况下,该器件可能无法正常工作,所以不建议
让器件在这些条件下长期工作。此外,长期在高于推荐的工作条件下工作,会影响器件的可靠性。绝对最大额定值仅是
应力规格值。除非另有说明, TA= 25°C。
