Introduction

The 1EDI2002AS 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 1EDI2002AS 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).
