Description  
EiceDRIVER1EDNx550 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  
4-pin packages (Kelvin Source connection)  
high parasitic PCB inductances (long distances, single-layer PCB)  
bipolar gate drive  
In addition, within the common-mode voltage range CMR for PWM signal at 3.3 V as in (Table 1), 1EDNx550  
allows to address even high-side and half-bridge applications. For PWM signals other than 3.3. V please see the  
Application note Applications of 1EDNx550 single-channel lowside EiceDRIVERwith truly differential inputs.
