The MAX5048A/MAX5048B are high-speed MOSFET
drivers capable of sinking/sourcing 7.6A/1.3A peak cur-
rents. These devices take logic input signals and drive
a large external MOSFET. The MAX5048A/MAX5048B
have inverting and noninverting inputs that give the
user greater flexibility in controlling the MOSFET. They
feature two separate outputs working in complementary
mode, offering flexibility in controlling both turn-on and
turn-off switching speeds.
The MAX5048A/MAX5048B have internal logic circuitry,
which prevents shoot-through during output state
changes. The logic inputs are protected against volt-
age spikes up to +14V, regardless of V+ voltage.
Propagation delay time is minimized and matched
between the inverting and noninverting inputs. The
MAX5048A/MAX5048B have very fast switching times
combined with very short propagation delays (12ns
typ), making them ideal for high-frequency circuits.
The MAX5048A/MAX5048B operate from a +4V to +12.6V
single power supply and typically consume 0.95mA of
supply current. The MAX5048A has CMOS input logic
levels, while the MAX5048B has standard TTL input logic
levels. These devices are available in space-saving
6-pin SOT23 and TDFN packages.
