Features

  • Patented gate-sensed adaptive dead time control provides shoot-through protection and mimized dead time.
  • Unique tri-level PWM input for integration with Renesas multiphase controllers (for example, ISL78225 and ISL78226).
  • 3A sourcing and 4A sinking output current.
  • On-chip 3Ω bootsrap FET switch.
  • Programmable dead time delay with single resistor.
  • Tri-level PWM input (ISL78424, ISL78444).
  • Independent HI/LI inputs (ISL78434).

DATASHEET ISL78424, ISL78434, ISL78444 100V Boot, 4A Peak, Half-Bridge Driver with Single PWM Input and Adaptive Dead Time Control FN9357 Rev.0.00 Sep 10, 2018 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.
