1EDN7550B数据手册集成电路（IC）的栅极驱动器规格书PDF

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
