Description
The AUIR0815 buffer gate driver family, in conjunction with a pre-driver
stage, is suited to drive a single half bridge in power switching
applications. These buffer gate drivers incorporate the ability to enter into
a low quiescent current mode.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which permanent damage to the device may occur. These are stress
ratings only, functional operation of the device at these or any other condition beyond those indicated in the “Recommended
Operating Condition” is not implied. Exposure to absolute maximum-rated conditions for extended periods may affect device
reliability. All voltage parameters are absolute voltages referenced to GND unless otherwise stated in the table. The thermal
resistance and power dissipation ratings are measured under board mounted and still air conditions.
