illustrate

The LM5109 is a low-cost, high-voltage gate driver designed to drive high-side and low-side N-channel MOSFETs in synchronous buck or half-bridge configurations. The floating high-side driver is capable of working with rail voltages up to 100V. Independently controlled output with TTL-compatible input thresholds. A powerful level translator technology provides clean power consumption while low power consumption and control input logic level conversion to high-side gate drivers at high speeds. The low and high rails provide undervoltage lockout. The device is available in SOIC-8 and thermally enhanced LLP-8 packages.
