ISL78424, ISL78434, ISL78444 FN9357
Rev.0.00
Sep 10, 2018 100V Boot, 4A Peak, Half-Bridge Driver with Single PWM Input and Adaptive
Dead Time Control
The ISL78424, ISL78434, and ISL78444 are Automotive
Grade (AEC-Q100 Grade 1) high voltage, high
frequency, half-bridge NMOS FET drivers for driving
the gates of up to 70V half-bridge topologies.
The family of half-bridge drivers feature 3A sourcing,
4A sinking peak gate drive current. The ISL78424 and
ISL78444 feature a single tri-level PWM input for
controlling both gate drivers. The ISL78434 has dual
independent inputs for controlling the high-side and
low-side driver separately. The ISL78424 and ISL78434
have independent sourcing and sinking pins for each gate
driver while ISL78444 has a single combined
sourcing/sinking output for each gate driver.
Strong gate drive strength and the Adaptive Dead Time
(ADT) feature allow this family of drivers to switch high
voltage, low rDS(ON) power FETs in half-bridge
topologies at high operating frequencies while providing
shoot-through protection and minimizing dead time …
