FAD8253集成电路（IC）的栅极驱动器规格书PDF中文资料

FAD8253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FAD8253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。

Description

The FAD8253 is a monolithic half−bridge gate driver IC designed for driving high voltage, high speed and high power IGBTs up to +1200 V. The FAD8253 employs ON’s high−voltage process and common−mode noise canceling technique to provide stable operation of high−side driver under high dv/dt noise circumstances. The gate driver includes UVLO circuits tailored to IGBT threshold for both high side and low side outputs to prevent malfunction when VDD and VBS are lower than the specified threshold voltage.
