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.
Under
voltage lockout is provided on both the low side an...
