The EiceDRIVER™ 2EDi is a family of fast dual-channel isolated MOSFET gate-driver ICs providing functional (2EDFx) or reinforced (2EDSx) input-to-output isolation by means of coreless transformer (CT) technology. Due to high driving current, excellent common-mode rejection and fast signal propagation, 2EDi is particularly well suited for driving medium- to high-voltage MOSFETs (CoolMOS™, OptiMOS™, CoolSIC™) in fast-switching power systems.

The gate drivers of the EiceDRIVER™ 2EDi product family are designed for fast-switching, medium to high power systems with MOSFET switches. They are optimized for high timing accuracy over temperature and production spread. The reliable accurate timing simplifies system design and provides better power conversion efficiency.

The 2EDSx, 2EDFx dual-channel reinforced (safe) and functional isolated product variants are available with different drive strengths: 4 A/8 A for low-ohmic power MOSFETs, 1 A/2 A for higher Ron MOSFETs or slower switching transients (EMI). The 1 A/2 A reinforced isolation dri...
