L6569集成电路（IC）的栅极驱动器规格书PDF中文资料

L6569属于集成电路（IC）的栅极驱动器。由意法半导体集团制造生产的L6569栅极驱动器栅极驱动器电源管理集成电路 (PMIC) 可用于提供隔离、放大、参考位移、自举或其他必要功能，这些功能可将来自电源转换应用中控制设备的信号连接到电源被控制通过的半导体设备（通常为 FET 或 IGBT）。任何特定设备提供的确切功能各不相同，但与它适合驱动的半导体配置相关。

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.
