4A, 20ns, MOSFET Driver
General Description
The MAX5078A/MAX5078B high-speed MOSFET drivers
source and sink up to 4A peak current. These devices
feature a fast 20ns propagation delay and 20ns rise and
fall times while driving a 5000pF capacitive load.
Propagation delay time is minimized and matched
between the inverting and noninverting inputs. High
sourcing/sinking peak currents, low propagation delay,
and thermally enhanced packages make the MAX5078A/
MAX5078B ideal for high-frequency and high-power
circuits.
The MAX5078A/MAX5078B operate from a 4V to 15V
single power supply and consume 40µA (typ) of supply
current when not switching. These devices have an
internal logic circuitry that prevents shoot-through during
output state changes to minimize the operating current
at a high switching frequency. The logic inputs are pro-
tected against voltage spikes up to +18V, regardless of
the VDD voltage. The MAX5078A has CMOS input logic
levels while the MAX5078B has TTL-compatible input
logic levels.
The MAX5078A/MAX5078B feature both inverting and
noninverting inputs for greater flexibility in controlling the
MOSFET. They are available in a 6-pin TDFN (3mm x
3mm) package and operate over the automotive temper-
ature range of -40°C to +125°C.

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.
