MAX5048 7.6A, 12ns, SOT23/TDFN, MOSFET Driver General Description Features The MAX5048A/MAX5048B are high-speed MOSFET Independent Source-and-Sink Outputs for drivers capable of sinking/sourcing 7.6A/1.3A peak cur- Controllable Rise and Fall Times rents. These devices take logic input signals and drive +4V to +12.6V Single Power Supply a large external MOSFET. The MAX5048A/MAX5048B 7.6A/1.3A Peak Sink/Source Drive Current have inverting and noninverting inputs that give the user greater flexibility in controlling the MOSFET. They 0.23 Open-Drain n-Channel Sink Output feature two separate outputs working in complementary 2 Open-Drain p-Channel Source Output mode, offering flexibility in controlling both turn-on and 12ns (typ) Propagation Delay turn-off switching speeds. Matching Delay Time Between Inverting and The MAX5048A/MAX5048B have internal logic circuitry, Noninverting Inputs which prevents shoot-through during output state changes. The logic inputs are protected against volt- V /2 CMOS (MAX5048A)/TTL (MAX5048B) Logic CC age spikes up to +14V, regardless of V+ voltage. Inputs Propagation delay time is minimized and matched 1.6V Input Hysteresis between the inverting and noninverting inputs. The Up to +14V Logic Inputs (Regardless of V+ MAX5048A/MAX5048B have very fast switching times Voltage) combined with very short propagation delays (12ns typ), making them ideal for high-frequency circuits. Low Input Capacitance: 2.5pF (typ) The MAX5048A/MAX5048B operate from a +4V to +12.6V -40C to +125C Operating Temperature Range single power supply and typically consume 0.95mA of 6-Pin SOT23 and TDFN Packages supply current. The MAX5048A has CMOS input logic Ordering Information levels, while the MAX5048B has standard TTL input logic levels. These devices are available in space-saving PIN- LOGIC TOP 6-pin SOT23 and TDFN packages.
