IX332B 2.5 Amp Output Current IGBT Gate Driver Optocoupler INTEGRATED CIRCUITS DIVISION Features Description Under Voltage Lock-Out Protection (UVLO) with The IX332B is an advanced 2.5A output current, Hysteresis optically isolated, IGBT gate driver that integrates V CE Desaturation Detection desaturation detection, UVLO fault status feedback, Miller Clamping and active Miller clamping. Open Collector Isolated fault feedback The IX332B is constructed as a power optocoupler Soft IGBT Turn-off with 4250V isolation between the control input and rms Fault Reset by next LED turn-on (low to high) after power output stages. In addition, an optically isolated, fault mute period open-collector feedback circuit relays FAULT status to Available in 16-pin SOIC package the controller. Both optical isolation circuits employ highly efficient infrared LEDs. Applications Featuring soft IGBT turn-off, isolated fault feedback, Isolated IGBT/Power MOSFET gate drive under voltage lock-out with hysteresis, active Miller clamping, and V desaturation detection, the IX332B CE Approvals offers engineers design flexibility and maximum circuit UL 1577 Certified Component protection.
