FAN7171MX-F085集成电路（IC）的栅极驱动器规格书PDF中文资料

FAN7171MX-F085属于集成电路（IC）的栅极驱动器。由安森美半导体公司制造生产的FAN7171MX-F085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 FAN7171-F085 is a monolithic high−side gate drive IC that 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 current driving capability and minimum cross−conduction.

onsemi’s high−voltage process and common−mode noise-canceling

techniques provide stable operation of the high−side driver under

high-dv/dt noise circumstances. An advanced level−shift circuit offers

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

15 V.

The UVLO circuit prevents malfunction when VBS is lower than the

specified threshold voltage.

The high−current and low−output voltage-drop feature make this

device suitable for sustaining switch drivers and energy−recovery

switch drivers in automotive motor drive inverters, switching power

supplies, and high−power DC−DC converter applications.
