TC4421集成電路（IC）的柵極驅(qū)動(dòng)器規(guī)格書PDF中文資料

TC4421屬于集成電路（IC）的柵極驅(qū)動(dòng)器。由微芯科技股份有限公司制造生產(chǎn)的TC4421柵極驅(qū)動(dòng)器柵極驅(qū)動(dòng)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(lái)自電源轉(zhuǎn)換應(yīng)用中控制設(shè)備的信號(hào)連接到電源被控制通過(guò)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(dòng)的半導(dǎo)體配置相關(guān)。

General Description

The TC4421/TC4422 are high-current buffer/drivers capable of driving large MOSFETs and IGBTs.

These devices are essentially immune to any form of upset, except direct overvoltage or over-dissipation. They cannot be latched under any conditions within their power and voltage ratings. These parts are not subject to damage or improper operation when up to 5V of ground bounce is present on their ground terminals. They can accept, without damage or logic upset, more than 1A inductive current of either polarity being forced back into their outputs. In addition, all terminals

are fully protected against up to 4 kV of electrostatic discharge.
