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 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.
