SCALE Driver
2SD315AI UL Data Sheet
2SD315AI UL Dual SCALE Driver Core
for IGBTs and Power MOSFETs
Description
The SCALE drivers from CONCEPT are
based on a chip set that was
developed specifically for the reliable
driving and safe operation of IGBTs
and power MOSFETs.
The name “SCALE” is an acronym for the
most outstanding properties of the SCALE
series of drivers:
SCALE
=
Scaleable, Compact, All
purpose,
Low
cost and
Easy
to use.
The SCALE driver is a winning project of the
competition organized by “Technology Center
Switzerland 1998”. And ABB Switzerland AG honored the development of the SCALE
driver by distinguishing it as the “best power electronics project in 1998”.
