Input-to-output isolation

All EiceDRIVER™ 2EDi dual-channel isolated products are tested in accordance with their respective isolation

class.

• 2EDFx for functional isolation, typically used as primary-side controlled galvanically isolated driver.

Device part numbers: 2EDFxxxxK (2EDF7275K, 2EDF7235K) and 2EDFxxxxF (2EDF7275F, 2EDF9275F,

2EDF7175F)

• 2EDSx for reinforced safe isolation, typically used as secondary-side controlled isolated gate driver.

Device part numbers: 2EDSxxxxH (2EDS8165H, 2EDS9265H, 2EDS8265H)

In combination with the different package dimensions and material characteristics, e.g. WB DSO-16 wide-body

(PG-DSO-16-30), NB DSO-16 narrow-body (PG-DSO-16-11) or LGA - 13 at 5mm x 5mm (PG-TFLGA-13-1) the

maximum input-to-output and channel-to-channel creepage and clearance distances and the possible working

voltages of the IC as a semiconductor component are defined (see Table 18 to Table 29)

Note:

The achievable system isolation depends on PCB design, materials, manufacturing- and working

environment. It is the customer’s obligation to verify that the outlined semiconductor component

isolation of the 2EDSx, 2EDFx device fits to application, manufacturing, working environment and end

system saftey requirement standards.
