Additional Details:

The AUIRS2301STRPBF features a floating channel that can be used in bootstrap configurations, allowing for high-side gate driving with minimal external components. Its high dV/dt immunity ensures reliable operation even with fast switching transients. The matched propagation delay for both channels minimizes dead-time requirements in bridge circuits, further improving efficiency. The under-voltage lockout (UVLO) protection prevents the MOSFETs or IGBTs from operating in a linear region during start-up, protecting them from over-dissipation. The driver can operate from a gate drive supply voltage ranging from 10V to 20V and supports logic input voltages from -0.3V to VCC+0.3V.
