MAX15024/MAX15025
Single/Dual, 16ns, High Sink/Source
Current Gate Drivers
General Description
Features
The MAX15024/MAX15025 single/dual, high-speed
MOSFET gate drivers are capable of operating at fre-
quencies up to 1MHz with large capacitive loads. The
MAX15024 includes internal source-and-sink output
transistors with independent outputs allowing for control
of the external MOSFET’s rise and fall time. The
MAX15024 is a single gate driver capable of sinking an
8A peak current and sourcing a 4A peak current. The
MAX15025 is a dual gate driver capable of sinking a 4A
peak current and sourcing a 2A peak current. An inte-
grated adjustable LDO voltage regulator provides gate-
drive amplitude control and optimization.
o 8A Peak Sink Current/4A Peak Source Current
(MAX15024)
o 4A Peak Sink Current/2A Peak Source Current
(MAX15025)
o Low 16ns Propagation Delay
o 4.5 V to 28V Supply Voltage Range
o On-Board Adjustable LDO for Gate-Drive
Amplitude Control and Optimization
o Separate Output Driver Supply
The MAX15024A and MAX15025A/C accept transistor-
to-transistor (TTL) input logic levels while the
MAX15024B and MAX15025B/D accept CMOS-input
logic levels. High sourcing/sinking peak currents, a low
propagation delay, and thermally enhanced packages
make the MAX15024/MAX15025 ideal for high-frequency
and high-power circuits. The MAX15024/MAX15025
operate from a 4.5V to 28V supply. A separate output dri-
ver supply input enhances flexibility and permits a soft-
start of the power MOSFETs used in synchronous
rectifiers.
o Independent Source and Sink Outputs (MAX15024)
o Matched Delays Between Inverting and
Noninverting Inputs (MAX15024)
o Matched Delays Between Channels (MAX15025)
o CMOS or TTL Logic-Level Inputs with Hysteresis
for Noise Immunity
o -40°C to +125°C Operating Temperature Range
o Thermal-Shutdown Protection
The MAX15024/MAX15025 are available in 10-pin
TDFN packages and are specified over the -40°C to
+125°C automotive temperature range.
o 1.95W Thermally Enhanced TDFN Power Packages
