TC4421A屬于集成電路（IC）的柵極驅動器。由微芯科技股份有限公司制造生產(chǎn)的TC4421A柵極驅動器柵極驅動器電源管理集成電路 (PMIC) 可用于提供隔離、放大、參考位移、自舉或其他必要功能，這些功能可將來自電源轉換應用中控制設備的信號連接到電源被控制通過的半導體設備（通常為 FET 或 IGBT）。任何特定設備提供的確切功能各不相同，但與它適合驅動的半導體配置相關。

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.
