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

•

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 EiceDRIVER^™with truly diﬀerential inputs.
