MAX15024/MAX15025

Single/Dual, 16ns, High Sink/Source

Current Gate Drivers

General Description

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.

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.

The MAX15024/MAX15025 are available in 10-pin

TDFN packages and are specified over the -40°C to

+125°C automotive temperature range.
