NCP51705屬于開發(fā)板套件編程器的評估板-擴展板子卡。由安森美半導(dǎo)體公司制造生產(chǎn)的NCP51705評估板 - 擴展板，子卡評估和擴展板及子卡用于向微控制器平臺添加功能，它們可以堆疊到現(xiàn)有針座或預(yù)配置的附件端口上。常見功能類型包括放大器、霧化器、音頻、時鐘定時、接口連接性、數(shù)據(jù)獲取/記錄、顯示、人機界面、存儲器、電機驅(qū)動器、光電器件、電源管理、原型設(shè)計、繼電器和晶體管、RF 和傳感器陣列。

The NCP51705 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 NCP51705

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 NCP51705 also

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

of digital or high speed opto isolators.

The NCP51705 offers important protection functions such as

under?voltage lockout monitoring for the bias power and thermal

shutdown based on the junction temperature of the driver circuit.
