1EDN7550B中文资料具有真正差分输入的单通道非隔离栅极驱动器 IC 系列数据手册Infineon规格书

描述 Description

The 1EDN7550/1EDN8550 gate driver ICs have truly differential inputs. Their controlsignal inputs are largely independent from the ground potential. Only the voltage difference between its input contacts is relevant. This prevents false triggering of power MOSFETs.

特性 Features

• Truly differential inputs
• 4A source current
• 8A sink current
• Separate source/sink outputs
• Low-ohmic output stage
• 29ns input minimum pulse width
• 7ns propagation delay accuracy
• 5A reverse current robustness of the outputs
• 4V and 8V UVLO versions
• SOT-23 package, 6 pins

优势:
