7A Sink, 3A Source, 12ns, SOT23 MOSFET Drivers

The MAX25615 is a high-speed MOSFET driver IC for automotive applications. The driver is capable of sinking 7A and sourcing 3A peak currents. The IC, which is an enhancement over MAX5048 devices, has inverting and non-inverting inputs that provide greater flexibility in controlling the MOSFET. It also features two separate outputs working in complementary mode, offering flexibility in controlling both turn-on and turn-off switching speeds.

The IC has internal logic circuitry that prevents shoot-through during output-state changes. The logic inputs are protected against voltage spikes up to +16V, regardless of V+ voltage. Propagation delay time is minimized and matched between the inverting and non-inverting inputs. The IC has a very fast switching time, combined with short propagation delays (12ns typ), making it ideal for high-frequency circuits. The IC operates from a +4V to +15.5V single power supply and typically consumes 0.5mA of supply current. The MAX25615 has standard TTL input logic levels.

The MAX25615 is available in a 6-pin SOT23 package and operates over the -40&degC to +125°C temperature range.
