2EDF8275F

Overview

Fast, robust, dual-channel, functional isolated MOSFET gate drivers with accurate and stable timing

The EiceDRIVER™ 2EDF8275F is the perfect fit for robust and stable operation for primary side control of high- and low-side MOSFETs in noisy high-power switching environments. The strong 4A/8A source/sink dual-channel gate drivers provide a fast turn on/off when driving high- and medium-voltage MOSFETs such as CoolMOS™ or OptiMOS™. Both output channels are individually isolated and can be flexibly deployed as floating gate drivers with very high 150V/ns CMTI (Common Mode Noise Immunity).

The VDDi input supply supports a wide voltage range SLDO mode to save on-board LDOs. For slower switching or driving smaller MOSFETs, a 1A/2A peak current product variant, the EiceDRIVER™ 2EDF8275F, is available in the DSO-16 narrow body package with 4mm creepage distance.
