Maxim
Integrated
Products
released
its
latest
high-speed,
dual
MOSFET
driver
that
is
capable
of
dissipating
up
to
2W
at
70°C
ambient
temperature.
The
MAX5054
is
engineered
for
use
in
power
MOSFET
switching,
motor
control
and
the
design
of
ultra-compact,
high-frequency,
switching
power
supplies.
Each
MOSFET
driver
is
capable
of
sourcing
and
sinking
up
to
4A
peak
current
with
a
20ns
propagation
delay.
The
propagation-delay
matching
between
channels
is
typically
2ns
and
typically
less
than
±10ns
from
part
to
part.
According
to
Maxim,
the
product's
low
propagation
delay
over
the
supply
voltage
range
and
tight
delay
tolerance
between
devices
allow
excellent
control
when
driving
the
MOSFETs
in
push-pull
converters,
and
for
driving
secondary-side
synchronous
rectifiers
in
isolated
power
supplies.
The
MAX5054
is
rated
for
operation
from
a
4V
to
15V
supply
voltage
and
can
withstand
up
to
18V
transients.
The
driver
IC's
inverting
and
noninverting
logic
inputs
are
designed
to
operate
at
up
to
18V,
regardless
of
the
VDD
supply
voltage.
The
device
includes
a
logic
circuit
to
prevent
internal
shoot-through
current
during
output
state
change.
A
choice
of
either
VDD/2
CMOS
(MAX5054A)
or
TTL
(MAX5054B)
logic
input
is
available.
The
MAX5054
is
available
in
the
-40°C
to
125°C
automotive
temperature
range
in
a
3-by-3mm,
8-pin
thermally
enhanced
TDFN
package
with
exposed
pad.
The
TDFN
package
has
a
44
percent
smaller
footprint
than
commercially
available
FET
drivers
in
LLP
packages
and
is
71
percent
smaller
than
the
8-pin
SO
package.
Prices
start
at
78
cents
