DEIC421集成電路（IC）的柵極驅(qū)動(dòng)器規(guī)格書(shū)PDF中文資料

DEIC421屬于集成電路（IC）的柵極驅(qū)動(dòng)器。由IXYS Corporation制造生產(chǎn)的DEIC421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)。

Description

The DEIC421 is a CMOS high speed high current gate driver specifically designed to drive MOSFETs in Class D, E, and RF applications at up to 45MHz, as well as other applications requiring ultrafast rise and fall times or short minimum pulse widths. The DEIC421 is an improved version of the DEIC420. The DEIC421 has a Kelvin ground connection on the input side to allow the use of a common mode choke to avoid problems with ground bounce. The internal layout of the package has been improved to reduce inductance. The DEIC421 can source and sink 20A of peak current while producing voltage rise and fall times of less than 4ns, and minimum pulse widths of 8ns. The input of the driver is compatible with +5V or CMOS and is fully immune to latch up over the entire operating range. Its features and wide safety margin in operating voltage and power make the DEIC421 unmatched in performance and value.
