Texas Instruments LM5109MA/NOPB

100V 1A/1A peak half-bridge gate driver with 7V UVLO 8-SOIC

MOSFET DRVR 100V 1A 2-OUT Hi/Lo Side Half Brdg Non-Inv 8-Pin SOIC N Rail

The LM5109 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 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.
