LM5109B High
Voltage 1A Peak Half Bridge Gate Driver
General 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 compatible input thresholds.
The robust level shift 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.
