systems in automotive applications, in which
effi ciency, space savings, and monitoring functions
are mandatory requirements, according to Infi neon.
The EiceDRI ER offers stable operation in harsh
EMC environments and drives up to 100-A 1,200-
IGBTs with its integrated 2-A output stage. Collec-
tor-emitter saturation voltage ( CE(sat) ) detection
and active Miller clamp features complete the
layout of this IGBT driver IC family.
Infi neon’s 2ED020I12FA E ALKIT, shown
in Figure 2, is an evaluation board for the
2ED020I12FA dual-channel isolated IGBT driver for
600- 1,200- IGBTs. The board allows designers
to accelerate the development phase of critical
automotive projects, evaluating the functionalities
offered by the EiceDRI ER device family.
