1200V half bridge driver IC family is rugged for high power systems
Infineon Technologies has expanded its EiceDriver range with the 2ED132xS12x family. The half bridge configuration of the driver IC family complements the existing 1200V SOI series, with increased output current capability and extends the applicability of the portfolio to higher system power levels.
The SOI driver ICs are claimed to offer industry-leading negative VS transient immunity, shoot-through protection, under-voltage lockout and fast over-current protection. These features 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 10kW.
These half bridge driver ICs include four versions in two different packages. The 2ED132xS12M is in a DSO-16 300 mil package and provides +2.3A / -4.6A current capability. The 2ED132xS12P is in a DSO-20 300 mil package and supports +2.3A / -2.3A drive capability. The company claimed that the family features best in class switching performance in packages with sufficient creepage and clearance distances. They integrate a low resistance (30 Ohm) bootstrap diode, fast and accurate (± 5 per cent tolerance) over-current protection (OCP), 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 and short circuit clamp.
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 100V during repeated 700 nanosecond pulses. The devices are RoHS-compliant and resistant to electrostatic discharge (ESD) and moisture.
The EiceDRIVER 2ED132X series can be ordered now. The 2ED132x + 1200V SiC EASY1B PIM evaluation board will be available soon, confirmed Infineon.
The EiceDRIVER family will be presented at PCIM Europe 2023 – Hall 7 – 412.
