TC4451VAT屬于集成電路（IC）的柵極驅(qū)動器。由微芯科技股份有限公司制造生產(chǎn)的TC4451VAT柵極驅(qū)動器柵極驅(qū)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(zhuǎn)換應用中控制設(shè)備的信號連接到電源被控制通過的半導體設(shè)備（通常為 FET 或 IGBT）。任何特定設(shè)備提供的確切功能各不相同，但與它適合驅(qū)動的半導體配置相關(guān)。

General Description

The TC4451/TC4452 are single-output MOSFET drivers. These devices are high-current buffer/drivers capable of driving large MOSFETs and Insulated Gate Bipolar Transistors (IGBTs). The TC4451/TC4452 have matched output rise and fall times, as well as matched leading and falling-edge propagation delay times. The TC4451/TC4452 devices also have very low cross conduction current, reducing the overall power dissipation of the device.
