低压 MOSFET 驱动器

意法半导体面向MOSFET和IGBT的单重栅极驱动器实现了高集成度,降低了BOM成本和终端应用尺寸,同时还提高了稳定性和抗扰度。 

PM8851 and PM8841 - single MOSFET drivers

PM8851 and PM8841 offer an optimized solution for driving low side MOSFET in designs where the controller has no high current/high voltage drive capability which is typically the case in digital SMPS or lighting power conversion designs.

Key Features

  • 1 A sink and 0.8 A source capability
  • External reference for input threshold
  • Wide supply voltage range (10 V ÷ 18 V)
  • Input and output pull-down resistors
  • Short propagation delays
  • Input and output UVLO
  • Wide operating temperature range: -40 °C to 125 °C

PM8841, that features a split sink/source path for further design optimization, comes in SOT23-6 while PM8851 comes in SOT23-5 package.
