概览

FAN3121 和 FAN3122 MOSFET 驱动器设计为通过提供高峰值电流脉冲来驱动低侧开关应用中的 N 沟道增强型 MOSFET。此类驱动器可以提供TTL (FAN312xT)或CMOS (FAN312xC)输入阈值。内部电路可使输出保持低电平状态，直到电源电压进入工作范围，从而提供欠压锁定功能。
FAN312x 驱动器内置用于最终输出级的 MillerDrive™ 架构。这一双极性/MOSFET 组合可在 MOSFET 开/关过程的米勒平台区域期间提供最高的峰值电流。
FAN3121 和 FAN3122 驱动器在引脚 3 (EN)上实施使能功能，这在过去业界标准引脚排列上未曾用过。该引脚于内部上拉至VDD以获得高电平有效逻辑，并可保持开路以实现标准运行。
FAN3121/22 采用 3x3 mm 8 引脚耐热增强型 MLP 封装或 8 引脚 SOIC 封装。

  • AC-DC商用电源-服务器和工作站
  • 带使能输入的业界标准引脚排列
  • 4.5 到 18 V 工作范围
  • 11.4 A 峰值灌电流, VDD = 12 V
  • 9.7A灌电流/7.1A源电流，VOUT = 6 V
  • 反相配置(FAN3121)和同相配置(FAN3122)
  • 无输入时内部电阻关闭驱动器
  • 10nF负载时具有23ns/19ns（典型值）的上升/下降时间
  • 20ns典型传播延迟时间
  • 可选择 TTL 或 CMOS 输入阈值
  • MillerDrive™ 技术
  • 以热保护增强3x3毫米 8引脚MLP或8引脚SOIC封装（无铅工艺）形式提供
  • 额定温度为 –40°C 到 +125°C
