100V Half-Bridge GaN Driver with Smart Integrated Bootstrap Switch FEATURES GENERAL DESCRIPTION  Half-Bridge Gate Driver for GaN FETs The LT8418 is a 100V half-bridge GaN driver that
integrates top and bottom driver stages, driver logic
control, and protections. It can be configured into
synchronous half-bridge, full-bridge topologies, or
buck, boost, and buck-boost topologies. The LT8418
provides strong current sourcing/sinking capability with
0.6Ω pull-up and 0.2Ω pull-down resistance. It also
integrates smart integrated bootstrap switch to
generate a balanced bootstrap voltage from VCC with a
minimum dropout voltage.  0.6Ω Pull-Up Resistance at Top Gate Driver
 0.2Ω Pull-Down Resistance at Bottom Gate Driver
 4A Peak Source, 8A Peak Sink Current Capability
 Smart Integrated Bootstrap Switch
 Split-Gate-Driver to Adjust Turn-On/Turn-Off Strength
 Default Low-State for All Driver Inputs and Outputs
 Maximum 15V Voltage Rating at INT and INB Inputs The LT8418 provides split gate drivers to adjust the turnon and turn-off slew rates of GaN FETs to suppress
ringing and optimize EMI performance. All driver inputs
and outputs have default low-state to prevent GaN FETs
from false turn-on. The inputs of the LT8418, INT, and
INB are independent and TTL logic compatible.
Meanwhile, the LT8418 performs with a fast propagation
delay of 10ns and maintains an excellent delay matching …
