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 driver can also be used as a PWM Data Coupler in combination with a non-isolated boost gate driver such as 1EDNx 4 A/8 A placed in closest proximity to the Superjunction power switches. Two independent and galvanically isolated gate driver channels ensure that all 2EDi versions can be used in any possible configuration of low- and high-side switches. Improved system robustness is supported by min. 150 V/ns Common Mode Transient Immunity (CMTI), PWM inputs with 18 ns noise filter, UVLO on output side including a safety self-lock-down of driver outputs in case of input UVLO (VDDI < 3 V), PWM outputs with up to 5 A peak reverse current capability and an intrinsically robust gate driver design.
