Application Hints
IMPORTANT INFORMATION
This data sheet contains only product-specific data. All data that apply
to the whole type series of SCALE drivers is given in the document
entitled: “Description and Application Manual for SCALE Drivers”. In
particular, this manual contains a detailed description of the concept of
the SCALE drivers, a description of the function of all terminal pins as
well as other important application hints.
Overview and application
The SCALE driver 6SD106E is a six-pack driver for power MOSFETs and IGBTs.
The terminal pins of the 6SD106E driver are arranged so that the layout can be kept
very simple and the logic signal flow (input signal
⇒ drive circuit ⇒ power transistors) is
maintained. A distance of 12.7mm is observed between the drive signal and the power
potential!
Collector sense and dimensioning of Rth
The
6SD106E
six-
path driver has a
collector-sense circuit
to protect the power
semiconductors. It is
shown in Fig. 4
Its basic operating
mode can be ob-
tained
from
the
brochure
entitled:
“Description
and
Application
Manual
for Scale Drivers”.
