SNVS412C – APRIL 2006 – REVISED SEPTEMBER 2016 LM5109A High Voltage 1A Peak Half Bridge Gate Driver
1 Features 3 Description The LM5109A 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 highside 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. Under-voltage lockout is provided on both
the low-side and the high-side power rails. The
device is available in the SOIC and the thermally
enhanced WSON packages. 1 Drives Both a High-Side and Low-Side N-Channel
