Overview
LM5109 100V / 1A Peak Half Bridge Gate Driver April 2005 LM5109 100V / 1A Peak Half Bridge Gate Driver General Description 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.
Undervoltage lockout is provided on both the low side an...
