4A, 20ns, Dual MOSFET Drivers
General Description
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 highfrequency 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 VDD 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. ♦ 4V to 15V Single Power Supply ♦ 4A Peak Source/Sink Drive Current ♦ 20ns (typ) Propagation Delay ♦ Matching Delay Between Inverting and Noninverting Inputs ♦ Matching Propagation Delay Between Two Channels ♦ VDD / 2 CMOS Logic Inputs (MAX5054AATA) ♦ TTL Logic Inputs (MAX5054B/MAX5055/MAX5056/MAX5057) ♦ 0.1 x VDD (CMOS) and 0.3V (TTL) Logic-Input Hysteresis ♦ Up to +18V Logic Inputs (Regardless of VDD Voltage) ♦ Low Input Capacitance: 2.5pF (typ) ♦ 40µA (typ) Quiescent Current ♦ -40°C to +125°C Operating Temperature Range ♦ 8-Pin TDFN and SO Packages

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
