SNVS477C – FEBRUARY 2007 – REVISED JANUARY 2016 LM5109B High Voltage 1-A Peak Half-Bridge Gate Driver
1 Features 3 Description The LM5109B device 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 90 V. The outputs are independently
controlled
with
cost-effective
TTL
and
CMOS-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. Undervoltage lockout is provided on both …
