LM5104
High Voltage Half-Bridge Gate Driver with Adaptive
Delay
General 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 is capable of working with supply voltages up to 100V.
The high side and low side gate drivers are controlled from a
single input. Each change in state is controlled in an adap-
tive 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.Arobust 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. Under-voltage lockout is provided on both the
low side and the high side power rails. This device is avail-
able in the standard SOIC-8 pin and the LLP-10 pin pack-
ages.
