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 r
DS(ON)
power FETs in half-bridge
topologies at high operating frequencies while providing
shoot-through protection and minimizing dead time
switching losses.
The ISL78424, ISL78434, and ISL78444 are offered in a 14
Ld HTSSOP package that complies with 100V conductor
spacing per IPC-2221B. The ISL78444 is pin compatible
with the ISL78420. All devices are specified across a
wide ambient temperature range of -40°C to +140°C.

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)
• Separate source/sink pins at driver outputs
(ISL78424, ISL78434)
• Bootstrap and VDD Undervoltage Lockout (UVLO)
• Wide supply range: 8V to 18V
• Bootstrap supply maximum voltage: 100V
• Maximum phase voltage: 86V
• Minimum phase voltage: -10V
Applications
• Automotive half-bridge and 3-phase motor driver
• 12V to 24V and 12V to 48V bidirectional DC/DC
(with ISL78226, ISL78224 controllers)
• Multi-phase boost (with ISL78220 and ISL78225
controllers)
