The galvanically isolated driver components are based on the Coreless Transformer Technology developed by Infineon, which enables output currents of up to 6 A on separate output pins.
The basic system includes UVLO (under voltage lockout) for IGBTs and MOSFETs as well as an active shutdown in the event that the driver is not connected to the power supply. The 1EDI drivers are supplied in a compact DSO-8 housing and can be used at ambient temperatures of up to 125°C in applications such as industrial drives, inverters, welding equipment, induction cooking appliances and power supplies for servers or telecommunications.
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 claim to be the first driver ICs to achieve a value of 100 kV/µs for the CMTI (common mode transient immunity). Both the MOSFET as well as one IGBT driver supply 6 A of output current. The MOSFET driver is optimized for use with power semiconductors that are based on CoolMOS technology. Owing to lower induction loss, the EiceDRIVER 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 A are in preparation. The 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 A of output current.
In addition to the compact class, the EiceDRIVER family also includes the EiceDRIVER Enhanced class which offers increased functionality both for the industrial as well as partially the consumer sectors.
