LM5109B Description

The LM5109B is a cost effective, 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 90V. The outputs are independently controlled with TTL patible input thresholds.

LM5109B Key Features

  • Drives both a high-side and low-side N-Channel MOSFET 1A peak output current (1.0A sink / 1.0A source) Independent TTL p
  • SOIC-8
  • LLP-8 (4 mm x 4 mm)
