FAD7191集成电路（IC）的栅极驱动器规格书PDF中文资料

FAD7191属于集成电路（IC）的栅极驱动器。由安森美半导体制造生产的FAD7191栅极驱动器栅极驱动器电源管理集成电路 (PMIC) 可用于提供隔离、放大、参考位移、自举或其他必要功能，这些功能可将来自电源转换应用中控制设备的信号连接到电源被控制通过的半导体设备（通常为 FET 或 IGBT）。任何特定设备提供的确切功能各不相同，但与它适合驱动的半导体配置相关。

描述 Description

The FAN7191 / FAD7191 is a monolithic high− and low−side

gate−driver IC, which can drive high speed MOSFETs and IGBTs that

operate up to +600 V. It has a buffered output stage with all NMOS

transistors designed for high pulse driving capability and minimum

cross−conduction.

ON Semiconductor’s high−voltage process and common−mode

noise canceling technique provide stable operation of high−drivers

under high dV/dt noise circumstances. An advanced level−shift circuit

allows high−side gate driver operation up to VS = −9.8 V (typical) for

VBS = 15 V.

The UVLO circuit prevents malfunction when VDD and VBS are

lower than the specified threshold voltage.

The high current and low output voltage drop features make this

device suitable for controlling direct injection actuators and for use in

many automotive DC−DC converter and motor control applications.
