illustrate

LM5109A is a cost-effective, high-voltage gate driver designed to drive two high-side and low-side N-channel MOSFETs in either a synchronous buck or half-bridge configuration. The floating high-side driver is capable of working with rail voltages up to 90V. Independently controlled output with TTL-compatible input thresholds. Powerful level-shifting technology provides clean power consumption while low power consumption and control input logic level conversion to high-side gate drivers at high speeds. Two low- and high-side power rails provide undervoltage lockout. The device is available in SOIC-8 and thermally enhanced LLP-8 packages.
