TC4427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TC4427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 TC4426/4427/4428 are improved versions of the earlier TC426/427/428 family of buffer/drivers (with which they are pin compatible). They will not latch up under any conditions within their power and voltage ratings. They are not subject to damage when up to 5V of noise spiking (of either polarity) occurs on the ground pin. They can accept, without damage or logic upset, up to 500mA of reverse current (of either polarity) being forced back into their outputs. All terminals are fully protected against up to 4kV of electrostatic discharge.
