Infineon has developed a half bridge gate driver with active Miller clamp for 1200V rugged power designs.

The EiceDRIVER 2ED132xS12x family extends the output current beyond the previous EiceDRIVER 6ED223xS12T 1200 V Silicon-on-Isolator (SOI) 3-phase gate driver.

The devise boost the negative VS transient immunity, shoot-through protection, undervoltage lockout and fast overcurrent protection. These reduce the bill of materials and enable a more rugged design with a compact form factor suitable for high power applications such as commercial HVAC systems, heat pumps, servo drives, industrial inverters, pumps and fans up to 10 kW.

These half-bridge driver ICs include four versions in two different packages: The 2ED132xS12M comes in a DSO-16 300 mil package and provides +2.3 A / -4.6 A current capability. While the 2ED132xS12P comes in a DSO-20 300 mil package and supports +2.3 A / -2.3 A current drive capability.

They integrate a low resistance 30 Ω bootstrap diode, overcurrent protection with ± 5% tolerance, enable input, fault-out, and programmable fault reset with separate logic (VSS) and output ground (COM) pins. The 2ED132xS12M variant provides additional features of Active Miller Clamp (AMC) and Short Circuit Clamp (SCC).

Infineon’s SOI technology eliminates the parasitic thyristor structure and provides excellent robustness and immunity to negative transient voltages on the VS pin. This results in guaranteed immunity to -VS transients of 100 V during repeated 700-ns pulses. In addition, the devices are RoHS compliant and resistant to electrostatic discharge (ESD) and moisture.

The EiceDRIVER 2ED132X series can be ordered now. In addition, the 2ED132x + 1200 V SiC EASY1B PIM evaluation board will be available in the coming months.
