| Data Sheet No. PD60026-O IR2112(S) HIGH AND LOW SIDE DRIVER Features * Floating channel designed for bootstrap * Fully operational to +600V * Tolerant to negative transient voltage dV/dt immune operation Product Summary VOFFSET IO+/VOUT ton/off (typ.) Delay Matching 600V max. 200 mA / 420 mA 10 - 20V 125 & 105 ns 30 ns * Gate drive supply range from 10 to 20V * Undervoltage lockout for both channels * 3.3V logic compatible * * * * Separate logic supply range from 3.3V to 20V Logic and power ground 5V offset CMOS Schmitt-triggered inputs with pull-down Cycle by cycle edge-triggered shutdown logic Matched propagation delay for both channels Outputs in phase with inputs Packages Description The IR2112(S) 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 rugge16-Lead SOIC dized monolithic construction. Logic inputs are com(wide body) 14-Lead PDIP patible with standard CMOS or LSTTL outputs, down to 3.3V logic. The output drivers feature a high pulse current buffer stage designed 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. Typical Connection HO VDD HIN SD LIN VSS VCC VDD HIN SD LIN VSS VCC COM LO VB VS up to 600V TO LOAD (Refer to Lead Assignments for correct pin configuration). This/These diagram(s) show electrical connections only. Please refer to our Application Notes and DesignTips for proper circuit board layout. www.irf.com 1 IR2112(S) 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.
