MAX25615
7A Sink, 3A Source,
12ns, SOT23 MOSFET Driver
General Description
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
noninverting inputs that provide greater flexibility in con-
trolling the MOSFET. It also features two separate outputs
working in complementary mode, offering flexibility in con-
trolling 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 noninverting 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°C to +125°C temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
