NCV51705集成電路（IC）的柵極驅(qū)動器規(guī)格書PDF中文資料

NCV51705屬于集成電路（IC）的柵極驅(qū)動器。由安森美半導(dǎo)體公司制造生產(chǎn)的NCV51705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)。

The NCV51705 driver is designed to primarily drive SiC MOSFET

transistors. To achieve the lowest possible conduction losses, the

driver is capable to deliver the maximum allowable gate voltage to the

SiC MOSFET device. By providing high peak current during turn?on

and turn?off, switching losses are also minimized. For improved

reliability, dV/dt immunity and even faster turn?off, the NCV51705

can utilize its on?board charge pump to generate a user selectable

negative voltage rail.

For full compatibility and to minimize the complexity of the bias

solution in isolated gate drive applications the NCV51705 also

provides an externally accessible 5 V rail to power the secondary side

of digital or high speed opto isolators.

The NCV51705 offers important protection functions such as

under?voltage lockout monitoring for the bias power.
