IR2238Q

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.
