E-L6569集成電路（IC）的柵極驅(qū)動器規(guī)格書PDF中文資料

E-L6569屬于集成電路（IC）的柵極驅(qū)動器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的E-L6569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)。

DESCRIPTION

The device is a high voltage half bridge driver with

built in oscillator. The frequency of the oscillator can

be programmed using external resistor and capacitor. The internal circuitry of the device allows it to be

driven also by external logic signal.

The output drivers are designed to drive external nchannel power MOSFET and IGBT. The internal logic assures a dead time [typ. 1.25μs] to avoid crossconduction of the power devices.

Two version are available: L6569 and L6569A. They

differ in the low voltage gate driver start up sequence.
