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 working in complementary mode, offering flexibility in controlling both turn-on and turn-off switching speeds.
The ICs have internal logic circuitry that prevents shootthrough 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 ICs have a very fast switching time, combined 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
operate over the -40NC to +125NC temperature range.
