SI9912DY-T1集成電路（IC）的柵極驅(qū)動(dòng)器規(guī)格書PDF中文資料

SI9912DY-T1屬于集成電路（IC）的柵極驅(qū)動(dòng)器。由威世科技半導(dǎo)體制造生產(chǎn)的SI9912DY-T1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(dòng)的半導(dǎo)體配置相關(guān)。

DESCRIPTION

The Si9912 is a dual MOSFET high-speed driver with break-before-make. It is designed to operate in high frequency dc-dc switchmode power supplies. The high-side driver is bootstrapped to handle the high voltage slew rate associated with “floating” high-side gate drivers. Each driver is capable of switching a 3000-pF load with 60-ns propogation delay and 25-ns transition time. The Si9912 comes with an internal break-before-make feature to prevent shoot-through current in the external MOSFETs. A shutdown pin is used to enable the driver. When disabled, the quiescent current of the driver is less than 5
A.
