Packages
The IR2112 is a high voltage, high speed power
MOSFET and IGBT driver with independent high and
low side referenced output channels. Proprietary
HVIC and latch immune CMOS technologies enable
ruggedized monolithic construction. Logic inputs are
compatible with standard CMOS or LSTTL outputs.
The output drivers feature a high pulse current buffer
stage designed for minimum driver cross-conduc-
tion. Propagation delays are matched to simplify
use in high frequency applications. The floating
channel can be used to drive an N-channel power
MOSFET or IGBT in the high side configuration
which operates up to 600 volts.

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. Additional information is shown in Figures 28 through 35.

Recommended Operating Conditions
The Input/Output logic timing diagram is shown in Figure 1. For proper operation the device should be used within the
recommended conditions. The VS and VSS offset ratings are tested with all supplies biased at 15V differential. Typical
ratings at other bias conditions are shown in Figures 36 and 37.

VBIAS (VCC, VBS, VDD) = 15V, TA = 25°C and VSS = COM unless otherwise specified. The VIN, VTH and IIN parameters are
referenced to VSS and are applicable to all three logic input leads: HIN, LIN and SD. The VO and IO parameters are
referenced to COM and are applicable to the respective output leads: HO or LO.
