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. SOT23-6 TSNP-6 Product features Topologies Very large common-mode input voltage 4-pin Kelvin-source MOSFETs in boost PFCs range (CMR static) up to 200 V, configurable Low-side driving with high PCB parasitic inductance with common mode resistors High-side driving in switched tank converters Separate low impedance source (4 A) and High and low-side driving in half and full-bridges sink (8 A) outputs Driving SJ and SiC MOSFETs, GaN HEMTs 45 ns propagation delay (-7/+10 ns accuracy) Switches requiring negative drive voltage Four UVLO options: 4 V, 8 V, 12 V and 15 V Applications SOT23-6 or TSNP-6 small packages Fully qualified according to JEDEC for Server, telecom and industrial SMPS industrial grade applications DC-DC converters and bricks Power tools, motor control Table 1 Product portfolio 1) 1) Part number Package UVLO ON/OFF Output current Max.
