General Description

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 a

space-saving 6-pin SOT23 package.
