The IR2137/IR2237(J)(Q) are a high voltage, high speed 3-phase IGBT driver best suited for AC motor drive applications. Integrated desaturation logic provides ground fault protection as well as other mode of over current protection. Soft shutdown is initiated in the event of any overcurrent/ground fault conditions, and all six outputs are simultaneously turned off. Output drivers have separate turn on/off pins to facilitate independent gate drive impedance with EMI soft turn on. Optimum matched delays between phases, and between high/low side enables small deadtime, thus improving low speed performance. The brake driver eliminates additional circuits.
