MAX15070A/MAX15070B

7A Sink, 3A Source,

12ns, SOT23 MOSFET Drivers

General Description

The MAX15070A/MAX15070B are high-speed MOSFET

drivers capable of sinking 7A and sourcing 3A peak

currents. The ICs, which are an enhancement over

MAX5048 devices, have inverting and noninverting

inputs that provide greater flexibility in controlling the

MOSFET. They also feature two separate outputs work-

ing in complementary mode, offering flexibility in control-

ling both turn-on and turn-off switching speeds.

The ICs have internal logic circuitry that prevents shoot-

through during output-state changes. The logic inputs

are protected against voltage spikes up to +16V, regard-

less of V+ voltage. Propagation delay time is minimized

and matched between the inverting and noninverting

inputs. The ICs have a very fast switching time, com-

bined with short propagation delays (12ns typ), making

them ideal for high-frequency circuits. The ICs operate

from a +4V to +14V single power supply and typically

consume 0.5mA of supply current. The MAX15070A has

standard TTL input logic levels, while the MAX15070B

has CMOS-like high-noise-margin (HNM) input logic

levels.

Both ICs are available in a 6-pin SOT23 package and
