Product brief
EiceDRIVER™ 2EDF7275F and 2EDF7175F
Fast, robust, dual-channel, functional isolated MOSFET gate drivers
with accurate and stable timing
Overview
The EiceDRIVER™ 2EDF7275F 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 4 A/8 A 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 150 V/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 1 A/2 A peak current product variant,
the EiceDRIVER™ 2EDF7175F, is available in the DSO-16 narrow body package with 4 mm
creepage distance.

The 2EDF7275F input-to-outputs are functional isolated, which is used today in larger power PCB designs or when seeking to isolate the
switching noise in the power loop from the microcontroller. With its >150 V/ns common mode noise immunity, the 2EDF is one of the
most robust solutions available today for high-side, low-side half-bridge topologies with simple CMOS level PWM inputs. The high-side
driver supply in the 2EDF can be implemented with a low cost bootstrap method.
The consistent performance and timing accuracy over temperature and production spread of the 2EDF family of isolated gate drivers
makes them easy to use within a power stage or across multi-phase, multi-level designs and enables further efficiency gains in high
performance power conversion applications.
