Infineon - EiceDRIVER™ 1EDS-SRC family

Infineon – EiceDRIVER™ 1EDS-SRC family

The new SRC EiceDRIVER™ family, which includes 1EDS20I12SV, 1EDU20I12SV, and 1EDI20I12SV, serves the latest generation of highly efficient low-EMI electric drive systems with lower EMI and improved efficiency. Based on the Infineon coreless trans-former technology, it is the first high-voltage isolated gate driver on the market with dy-namic Slew Rate Control (SRC) which allows on-the-fly dV/dt control of electric drives through precise gate current control, providing the best trade-off between minimum power dissipation and minimum EMI depending on operating conditions. To turn on the IGBT, the driver works as an adjustable current source in conjunction with an external PMOS transistors and a sense resistor. To turn off the IGBT, the driver uses a 2 A MOSFET output stage.
The 1EDx20I12SV family is tailored for industrial drive applications such as those using 1200 V power modules for currents up to 900 A like the EconoDUAL™ 3. The “S” versi-on 1EDS20I12SV provides reinforced galvanic isolation certification according to VDE 0884-10 and UL 1577. The ”U” version 1EDU20I12SV is UL 1577 certified with an isola-tion rating of VISO = 5000 V(rms) for 1 minute. The ”I” version 1EDI20I12SV provides functional isolation.
