STMicroelectronics L6743/L6743Q High Current MOSFET Driver Datasheet
The L6743 and L6743Q are flexible, high-frequency dual drivers specifically designed to drive N-channel MOSFETs connected in synchronous-rectified buck topology. These devices embed high-current drivers for both high-side and low-side MOSFETs and accept a flexible power supply ranging from 5 V to 12 V to optimize gate-drive voltage.

Questions answered in these manuals
What is the function of the integrated bootstrap diode?
The integrated bootstrap diode saves the use of external diodes in the circuit design.
From: STMicroelectronics L6743/L6743Q High Current MOSFET Driver Datasheet
What happens if the EN pin is pulled low?
Pulling the EN pin low causes the driver to enter the high-impedance (HiZ) state with all MOSFETs OFF.
