SNVS269D – JANUARY 2004 – REVISED DECEMBER 2014 LM5104 High-Voltage Half-Bridge Gate Driver With Adaptive Delay
1 Features 3 Description The LM5104 High-Voltage Gate Driver is designed to
drive both the high-side and the low-side N-channel
MOSFETs in a synchronous buck configuration. The
floating high-side driver can work with supply voltages
up to 100 V. The high-side and low-side gate drivers
are controlled from a single input. Each change in
state is controlled in an adaptive manner to prevent
shoot-through issues. In addition to the adaptive
transition timing, an additional delay time can be
added, proportional to an external setting resistor. An
integrated high-voltage diode is provided to charge
high-side gate drive bootstrap capacitor. A robust
level shifter operates at high speed while consuming
low power and providing clean level transitions from
the control logic to the high-side gate driver.
Undervoltage lockout is provided on both the low-side …
