SELF-OSCILLATING HALF-BRIDGE DRIVER IC

International Rectifier 

IRS2153(1)D

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, all currents are defined positive into any lead.

The thermal resistance and power dissipation ratings are measured under board mounted and still air

conditions.

Note 1: This IC contains a zener clamp structure between the chip VCC and COM which has a nominal

breakdown voltage of 15.4 V. Please note that this supply pin should not be driven by a DC, low

impedance power source greater than the VCLAMP specified in the Electrical Characteristics section.
