High-Voltage Power MOSFET and IGBT Driver


Clare's IX2127 is tolerant to negative transient voltages


Clare's IX2127 is a high-voltage, high speed power MOSFET and IGBT driver IC. High-voltage IC (HVIC) design methodology has been used to enable the IX2127 to drive N-channel power MOSFETs and IGBTs in the high-side configuration operating up to 600V. The IX2127 is extremely tolerant to negative transient voltages while providing excellent noise immunity.

SOI technology provides 'true' oxide isolation, which is a more rugged isolation than alternative junction isolation. Integrated protection features include supply undervoltage lockout, overcurrent detection and shutdown, and fault reporting. An onboard comparator can be used to detect an overcurrent condition in the driven MOSFET or IGBT device and then shut down drive to that device. An open-drain output, FAULT, indicates that an overcurrent shutdown has occurred. Datasheet
