EiceDRIVER™ 2EDi product family

2EDSx reinforced, 2EDFx functional isolated 4A/8A, 1A/2A gate drivers

Description

1.2

Input-to-output isolation testing

• 2EDSx Reinforced isolation (2EDSx in WB PG-DSO-16-30 package), for details see Table 26 to Table 29.

• Functional isolation (2EDFx in NB PG-DSO-16-11 and PG-TFLGA-13-1 packages), for details see Table 21 to

Table 23

1.3

Channel-to-channel isolation testing

• The functional isolation between the two channels are verified by the following tests

Application overview and system block diagram

2EDi gate drivers are perfectly suited to substitute bulky pulse transformers and drive power MOSFETs in half-

bridge configuration as depicted in Figure 1.

The input side is usually powered by the same power supply as the PWM controllers (VDDI = 3.3 V or VDDI > 3.5 V

if SLDO is activated). The output-side gate driver voltages VDDA, VDDB are generated by separate isolated

auxiliary supplies. In some topologies like LLC, the high side driver supply VDDA can be generated via a

bootstrapping circuitry.

For further application implementation guidance please refer to dedicated application notes.
