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 V

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.
