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.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters
are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured under board
mounted and still air conditions.

Recommended Operating Conditions
The Input/Output logic timing diagram is shown in figure 1. For proper operation the device should be used within the recom-
mended conditions. All voltage parameters are absolute voltages referenced to COM. The VS offset rating is tested with all
supplies biased at 15V differential.
