1EDN7550B

概要

1-channel low-side gate driver family with truly differential inputs prevents false triggering of power MOSFETs

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.
