4A, 20ns, Dual MOSFET Drivers
General Description
The MAX5054–MAX5057 dual, high-speed MOSFET
drivers source and sink up to 4A peak current. These
devices feature a fast 20ns propagation delay and 20ns
rise and fall times while driving a 5000pF capacitive
load. Propagation delay time is minimized and matched
between the inverting and noninverting inputs and
between channels. High sourcing/sinking peak cur-
rents, low propagation delay, and thermally enhanced
packages make the MAX5054–MAX5057 ideal for high-
frequency and high-power circuits.
The MAX5054–MAX5057 operate from a 4V to 15V single
power supply and consume 40µA (typ) of supply current
when not switching. These devices have internal logic
circuitry that prevents shoot-through during output state
changes to minimize the operating current at high
switching frequency. The logic inputs are protected
against voltage spikes up to +18V, regardless of the V
DD
voltage. The MAX5054A is the only version that has
CMOS input logic levels while the MAX5054B/MAX5055/
MAX5056/MAX5057 have TTL input logic levels.
The MAX5055–MAX5057 provide the combination of dual
inverting, dual noninverting, and inverting/noninverting
input drivers. The MAX5054 feature both inverting and
noninverting inputs per driver for greater flexibility. They
are available in 8-pin TDFN (3mm x 3mm), standard SO,
and thermally enhanced SO packages. These devices
operate over the automotive temperature range of -40°C
to +125°C.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
