Description
The IR2112(S) is ahigh voltage, high speed power
MOSFET and IGBT driver with independent high and
16-Lead SOIC (wide body)
low side referenced output channels. Proprietary HVIC
14-Lead PDIP
and latch immune CMOS technologies enable ruggedized monolithic construction. Logic inputs are compatible with standard CMOS or LSTTL outputs, down to 3.3V logic.
The output drivers feature a high pulse current buffer stagedesigned for minimum driver cross-conduction.
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.
