MP1909集成电路（IC）的栅极驱动器规格书PDF中文资料

MP1909属于集成电路（IC）的栅极驱动器。由美国芯源系统有限公司制造生产的MP1909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 MP1909 is a high-frequency, 30V, halfbridge,

N-channel power MOSFET driver. Its

low-side and high-side driver channels are

controlled by a signal input. Internal adaptive

dead time control circuitry reduces the switching

power loss and prevents shoot-through.

Both outputs are disabled when the EN pin is

pulled low. The integrated bootstrap diode

reduces external component count. Undervoltage

lockout (UVLO) functionality protects the

IC from operating at insufficient power supplies.

Thermal shutdown protection functions can

protect the IC from over-temperature conditions.
