Fully qualified for industrial applications according to JEDEC Description
EiceDRIVER™ 1EDNx550 is a new family of single-channel non-isolated gate-driver ICs. Due to the unique fully
differential input circuitry with excellent common-mode rejection, the logic driver state is exclusively controlled
by the voltage difference between the two inputs, completely independent of the driver’s reference (ground)
potential. This eliminates the risk for false triggering and thus is a significant benefit in all applications
exhibiting voltage differences between driver and controller ground, a problem typical for systems with
