Product Summary

The LM5109MAX/NOPB is a low cost high voltage gate driver, designed to drive both the high side and the low side N-Channel MOSFETs in a synchronous buck or a half bridge configuration. The floating high-side driver is capable of working with rail voltages up to 100V. The outputs of the LM5109MAX/NOPB are independently controlled with TTL compatible input thresholds. A robust level shifter technology operates at high speed while consuming low power and providing clean level transitions from the control input logic to the high side gate driver. Under-voltage lockout is provided on both the low side and the high side power rails. The device is available in the SOIC-8 and the thermally enhanced LLP-8 packages.
