LM5109 Overview

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 patible input thresholds.

LM5109 Key Features

  • 2 Drives Both a High Side and Low Side NChannel MOSFET
  • 1A Peak Output Current (1.0A Sink / 1.0A Source)
  • Independent TTL patible Inputs
  • Bootstrap Supply Voltage to 118V DC
  • Fast Propagation Times (27 ns Typical)
  • Drives 1000 pF Load with 15ns Rise and Fall
  • Excellent Propagation Delay Matching (2 ns
  • Supply Rail Under-voltage Lockout
  • Low Power Consumption
  • Pin patible with ISL6700
