Datasheet and Application
EiceDRIVER™ 2ED020I12-F
1
Overview
The 2ED020I12-F is a high voltage, high speed power IGBT and MOSFET driver of the eupec EiceDRIVER™ family with
interlocking high and low side referenced output channels. The floating high side driver may be supplied directly or by means
of a bootstrap diode and capacitor. In addition to the logic input of each driver the 2ED020I12-F is equipped with a dedicated
shutdown input. All logic inputs are compatible with 3.3 V and 5 V TTL. The output drivers feature a high pulse current buffer
stage designed for minimum driver cross-conduction. Propagation delays are matched to simplify use in high frequency appli-
cations. Both drivers are designed to drive an n-channel power IGBT or MOSFET which operates up to 1200 V. In addition, a
general purpose operational amplifier and a general purpose comparator are provided, which may be used e.g. for current
measurement or over current detection.

1.1
Coreless transformer (CLT) technology
In various IGBT and power MOSFET driver stages are optocoupler, level shifter or discrete transformer included to overcome
the isolation barrier between the low side input and high side output. All of them have their typical advantages and disadvan-
tages. As an alternative for low and medium power applications the coreless transformer technology combines almost all
advantages and at the same time avoiding almost all disadvantages of these devices by a very cost efficient way and high
voltage isolation capability.
The principle function of the CLT is realized by two coils which are compounded on silicon within one integrated circuit. The
isolation between these coils can withstand in the current design at least up to 1200 V whereby a functional isolation is
achieved. Figure 1 shows a schematic of the internal stages of the IC.
