Description

The MAX5055 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 cur-rents, low propagation delay, and thermally enhanced packages make the MAX5055 ideal for high-frequency and high-power circuits.

The MAX5055 operate from a 4V to 15V single power supply and consume 40A (typ) of supply current when not switching. The MAX5055 has 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 MAX5055 has TTL input logic levels.

The MAX5055 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. The MAX5055 operate over the automotive temperature range of -40°C to +125°C.
