2 / 17 page 2 www.irf.com IR2238Q Absolute Maximum Ratings (tentative) Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to COM, all currents are defined positive into any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions. Symbol Definition Min. Max. Units VS High side offset voltage VB1,2,3 -25 VB1,2,3 +0.3 VB High side floating supply voltage -0.3 1225 VHO High side floating output voltage (HOP, HON, HOQ) VS1,2,3 - 0.3 VB1,2,3 + 0.3 VCC Low side and logic fixed supply voltage -0.3 25 VSS Logic ground VCC - 25 VCC + 0.3 VLO Low side output voltage (LOP, LON, LOQ) -0.3 VCC + 0.3 VIN Logic input voltage (HIN/N,LIN, BRIN/N, SD)VSS - 0.3 VCC + 0.3 or VSS + 15 which ever is lower VFLT FAULT output voltage VSS - 0.3 VCC + 0.3 VF Feedback output voltage VSS - 0.3 VCC + 0.3 VDSH High side desat/feedback input voltage VS1,2,3 - 0.3 VB1,2,3 + 0.3 VDSL Low side desat/feedback input voltage - 0.3 VCC + 0.3 VBR Brake output voltage -0.3 VCC + 0.3 dVs/dt Allowable offset voltage slew rate — 50 V/ns PD Package power dissipation @ TA ≤ +25°C — 2.0 W RthJA Thermal resistance, junction to ambient — 60 TJ Junction temperature — 125 TS Storage temperature -55 150 TL Lead temperature (soldering, 10 seconds) — 300 °C/W V °C Recommended Operating Conditions For proper operation the device should be used within the recommended conditions. All voltage parameters are absolute voltages referenced to COM. The VS offset rating is tested with all supplies biased at 15V differential.
