STMicroelectronics L6743D Half-Bridge Gate Driver IC in a compact 8-SOIC package. This non-inverting driver is designed for controlling complementary power MOSFETs in half-bridge configurations. It features a peak output current capability of 2A source and sink, facilitating efficient switching of power devices. The L6743D supports a bootstrap voltage up to 41V, enabling operation with higher-side N-channel MOSFETs. Its logic input levels are compatible with standard microcontroller interfaces, with VIH at 2V and VIL at 0.8V. Operating within a supply voltage range of 5V to 12V and an ambient temperature range of 0°C to 125°C, this component is suitable for applications in power supply units and motor control systems that require robust and precise gate drive performance.
