The MAX5048C is a high-speed MOSFET driver capable of sinking/sourcing 7A/3A peak currents. This device takes logic input signals and drives a large external MOSFET. The device has inverting and noninverting inputs that give the user greater flexibility in controlling the MOSFET. The device also has the features necessary to drive low-side enhancement-mode Gallium Nitride (GaN) FETs. The device features two separate outputs working in complementary mode, offering flexibility in controlling both turn-on and turn-off switching speeds.

The device has 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 device has very fast switching times combined with very short propagation delays (8ns typ) making it ideal for high-frequency circuits.

The device operates from a +4V to +14V single power supply, typically consuming 0.5mA of supply current and has TTL input logic levels. This device is available in a 6-pin SOT23 package and provides an upgrade path for users of the MAX5048B.

Product Details

The MAX5048C evaluation kit (EV kit) allows evaluation of the MAX5048C high-speed, low-side MOSFET driver that can source up to a 3A peak current and sink up to a 7A peak current. The EV kit uses a 4V to 14V input supply. The EV kit uses the device to drive a 4700pF capacitor that mimics the gate capacitance of an external nMOSFET. The EV kit demonstrates the MAX5048CAUT+ (6-pin SOT23). It is highly recommended that the EV kit layout be followed to ensure reliable driver operation and first-pass design success.
