EiceDRIVER 1EDNx550

Single-channel high-side and low-side gate driver with high-CMR TDI inputs

Description

EiceDRIVER^™1EDNx550 is part of the TDI family of single-channel high-

side and low-side gate driver ICs. The TDI family has a fully diﬀerential

input circuitry. The truly diﬀerential inputs (TDI) provide excellent

common-mode robustness (CMR) and eliminates the risk of false

triggering. The small package footprints enable versatile layout in

both low-side and high-side driving.

range (CMR static) up to ±200 V, configurable

with common mode resistors

Separate low impedance source (4 A) and

sink (8 A) outputs

45 ns propagation delay (-7/+10 ns accuracy)

Four UVLO options: 4 V, 8 V, 12 V and 15 V

SOT23-6 or TSNP-6 small packages

Fully qualified according to JEDEC for

industrial grade applications

•

4-pin Kelvin-source MOSFETs in boost PFCs

Low-side driving with high PCB parasitic inductance

High-side driving in switched tank converters

High and low-side driving in half and full-bridges
