At the SPS IPC Drives trade fair, Infineon debuted its new 1EDI EiceDRIVER Compact Single Channel Gate Driver. Ideal for applications with isolation voltages of up to 1200 volts and based on Infineon's Coreless Transformer Technology, the 1EDI EiceDRIVER IC enables output currents of up to 6 amperes on separate output pins.

Included in the basic system is a under voltage lockout for IGBTs and MOFETs as well as an active shutdown in the event that the driver is not connected to the power supply. Supplied in a compact DSO-8 housing, the 1EDI drivers can be used at ambient temperatures of up to 125°C in applications such as industrial drives, inverters, and power supplies for servers or telecommunications.

Infineon's Oliver Hellmund commented; “The 1EDI Compact stands for exceptionally robust and simultaneously very secure control of high-voltage power semiconductors. Our compact driver range now covers all applications for power semiconductors with functional isolation.” The 1EDI driver ICs are offered in eight variants that can be operated at up to voltages of 1200 volts and are designed for use in applications with either IGBTs or MOSFETs.

The new EiceDRIVER components signal the first ICs to achieve a value of 100kV/µs for the common mode transient immunity, with both the MOSFET as well as one IGBT driver supply six amperes of output current. The MOSFET driver is optimized for use with power semiconductors that are based on CoolMOS™ technology. Due to lower induction loss, the EiceDRIVER™ thus enables an additional gain in efficiency of 0.5 percent with the latest generation CoolMOS C7. Further IGBT only variants with 4, 2 and 0.5 amperes are in preparation. These five variants have a separate output for charging and discharging the gate. An additional three variants are structured to limit the gate voltage (active Miller clamp) and provide 3, 2 and 1 amperes of output current.

The EiceDRIVER™ family also includes the EiceDRIVER, an enhanced class which offers increased functionality both for the industrial as well as partially the consumer sectors.

Samples of the 1EDI EiceDRIVER™ for MOSFETs and IGBTs with 6 amperes of output current are available now; the corresponding Customer Evaluation Board can be ordered as of January 2014. Production start for both these variants will presumably begin in March 2014. The other drivers are intended to be available as samples in the first quarter of 2014; production is planned to begin in the second quarter of 2014.
