Description
DESAT Blanking time (typ.)

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 pro-
DESAT input voltage

vides ground fault protection as well as other mode of
over current protection. Soft shutdown is initiated in Packages
the event of any overcurrent/ground fault conditions,
and all six outputs are simultaneously turned off. Out-
put 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.
