TC4420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TC4420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(yīng)用中控制設(shè)備的信號連接到電源被控制通過的半導(dǎo)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(dǎo)體配置相關(guān)。

GENERAL DESCRIPTION

The TC4420/4429 are 6A (peak), single output MOSFET drivers. The TC4429 is an inverting driver (pin-compatible with the TC429), while the TC4420 is a non-inverting driver. These drivers are fabricated in CMOS for lower power, more efficient operation versus bipolar drivers.
