Introduction
The 1EDI2004AS is an advanced single channel IGBT driver that can also be used for driving power MOS
devices. The device has been developed in order to optimize the design of high performance safety relevant
automotive systems.
The device is based on Infineon’s Coreless Transformer Technology and consist of two chips separated by a
galvanic isolation. The low voltage (primary) side can be connected to a standard 5 V logic. The high voltage
(secondary) side is in the DC-link voltage domain.
Internally, the data transfers are ensured by two independent communication channels. One channel is
dedicated to transferring the ON and OFF information of the PWM input signal only. This channel is
unidirectional (from primary to secondary). Because this channel is dedicated to the PWM information,
latency time and PWM distortion are minimized. The second channel is bidirectional and is used for all the
other data transfers (e.g. status information, etc).
The 1EDI2004AS supports advanced functions in order to optimize the switching behavior of the IGBT.
Furthermore, it supports several monitoring and protection functions, making it suitable for systems having
to fulfill ASIL requirements (as per ISO 26262).
