MAX5055

The MAX5054–MAX5057 dual, 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 and between channels. High sourcing/sinking peak currents, low propagation delay, and thermally enhanced packages make the MAX5054–MAX5057 ideal for high-frequency and high-power circuits.

The MAX5054–MAX5057 operate from a 4V to 15V single power supply and consume 40µA (typ) of supply current when not switching. These devices have internal logic circuitry that prevents shoot-through during output state changes to minimize the operating current at high switching frequency. The logic inputs are protected against voltage spikes up to +18V, regardless of the V_DD voltage. The MAX5054A is the only version that has CMOS input logic levels while the MAX5054B/MAX5055/MAX5056/MAX5057 have TTL input logic levels.

The MAX5055–MAX5057 provide the combination of dual inverting, dual noninverting, and inverting/noninverting input drivers. The MAX5054 feature both inverting and noninverting inputs per driver for greater flexibility. They are available in 8-pin TDFN (3mm x 3mm), standard SO, and thermally enhanced SO packages. These devices operate over the automotive temperature range of -40°C to +125°C.
