The STMicroelectronics L6743 is a high-performance, non-inverting half-bridge gate driver designed for driving N-channel MOSFETs in synchronous rectification applications. This 8-SOIC packaged component features two independent drivers, each capable of delivering 2A peak output current. The L6743 supports a high-side voltage of up to 41V, facilitated by its bootstrap capability. Operating with a supply voltage range of 5V to 12V, it is suitable for applications requiring precise switching control. The logic input voltage thresholds are specified at 0.8V for VIL and 2V for VIH, ensuring compatibility with standard logic families. This device is commonly utilized in power supply circuits, motor control systems, and power factor correction designs across various industrial sectors. The L6743 is provided in a tube for efficient handling and placement during manufacturing.
