LM5107
100V / 1.4A Peak Half Bridge Gate Driver
General Description
The LM5107 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 configura-
tion. 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. An inte-
grated on chip high voltage diode is provided to charge the
high side gate drive bootstrap capacitor. 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 and the high side power
rails. The device is available in the SOIC-8 and the thermally
enhanced LLP-8 packages.
