FAN3122TM1X-F085集成电路（IC）的栅极驱动器规格书PDF中文资料

FAN3122TM1X-F085属于集成电路（IC）的栅极驱动器。由安森美半导体制造生产的FAN3122TM1X-F085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。

描述 Description

The FAN3121 and FAN3122 MOSFET drivers are designed to drive

N−channel enhancement MOSFETs in low−side switching

applications by providing high peak current pulses. The drivers are

available with either TTL input thresholds (FAN312xT) or

VDD−proportional CMOS input thresholds (FAN312xC). Internal

circuitry provides an under−voltage lockout function by holding the

output low until the supply voltage is within the operating range.

FAN312x drivers incorporate the MillerDrive™ architecture for the

final output stage. This bipolar / MOSFET combination provides the

highest peak current during the Miller plateau stage of the MOSFET

turn−on / turn−off process.

The FAN3121 and FAN3122 drivers implement an enable function

on pin 3 (EN), previously unused in the industry−standard pin−out.

The pin is internally pulled up to VDD for active HIGH logic and can be

left open for standard operation.

The AEC−Q100 automotive−qualified versions are available in

8−lead SOIC packages with and without exposed pad.
