TC4422A集成电路（IC）的栅极驱动器规格书PDF中文资料

TC4422A属于集成电路（IC）的栅极驱动器。由微芯科技股份有限公司制造生产的TC4422A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 TC4421A/TC4422A are improved versions of the earlier TC4421/TC4422 family of single-output MOSFET drivers. These devices are high-current buffer/drivers capable of driving large MOSFETs and Insulated Gate Bipolar Transistors (IGBTs). The TC4421A/TC4422A have matched output rise and fall times, as well as matched leading and falling-edge propagation delay times. The TC4421A/TC4422A devices also have very low cross-conduction current, reducing the overall power dissipation of the device.
