Quality Control: Learn More
Texas Instruments LM5109AMA is a Half-Bridge Gate Driver IC, designed for efficient control of N-Channel MOSFETs in half-bridge configurations. This component features independent drivers with a 1A peak output current for both sourcing and sinking, enabling rapid switching. The gate driver supports a high-side bootstrap voltage up to 108V and operates with a supply voltage range of 8V to 14V. The non-inverting input simplifies control logic design. Typical rise and fall times are 15ns, facilitating high-frequency operation. The LM5109AMA is housed in an 8-SOIC package suitable for surface mounting, with an operating temperature range of -40°C to 125°C. This device finds application in power conversion systems, motor control, and power supply designs across industrial and automotive sectors.
