The MAX5048A/MAX5048B are high-speed MOSFET drivers capable of sinking/sourcing 7.6A/1.3A peak currents. 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 voltage 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 (12nstyp), 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.
