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 protected
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 temperature
range of -40°C to +125°C.
