Quality Control: Learn More
Texas Instruments LM5109ASDX is a half-bridge gate driver designed for high-side and low-side drive applications. This two-driver device features independent channels, each capable of sourcing and sinking 1A peak output current, facilitating efficient switching of N-channel MOSFETs. The driver supports a high-side bootstrap voltage up to 108V, with a supply voltage range of 8V to 14V. Its non-inverting input logic and low 0.8V/2.2V VIL/VIH thresholds ensure compatibility with various control signals. The typical rise and fall times of 15ns contribute to reduced switching losses. Packaged in an 8-WSON (4x4) with an exposed pad and supplied on tape and reel, the LM5109ASDX is suitable for surface mounting. This component finds application in power supply circuits, motor control, and other power conversion systems.
