Introduction

The SKYPER

®

42 LJ R is a two-channel driver core, which combines high output power with highly-

integrated ASIC technology in a very compact design. Its high reliability and EMC robustness makes the
SKYPER

®

42 LJ R suitable for a wide range of applications and sectors of many industries. The SKYPER

®

42

LJ R is designed to control semiconductor power modules with gate charges of typically up to 20µC and
provides reinforced isolation for operating voltages of up to 1200V. The interaction of the well-coordinated
functionality with the integrated safety functions makes the SKYPER

®

42 LJ R to a reliable control for power

semiconductor modules in standard, multilevel or parallel operation.
