TC4421MJA集成电路（IC）的栅极驱动器规格书PDF中文资料

TC4421MJA属于集成电路（IC）的栅极驱动器。由美国微芯科技公司制造生产的TC4421MJA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。

General Description

The TC4421M/TC4422M are high-current buffer/drivers capable of driving large MOSFETs and IGBTs.

They are essentially immune to any form of upset, except direct overvoltage or over-dissipation. They cannot be latched, under any conditions, within their power and voltage ratings. These parts are not subject to damage or improper operation when up to 5V of ground bounce is present on their ground terminals. They can accept, without damage or logic upset, more than 1A inductive current of either polarity being forced back into their outputs. In addition, all terminals are fully protected against up to 4 kV of electrostatic discharge.
