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 cur- rents, 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 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.

Detailed Description VDD Undervoltage Lockout (UVLO) The MAX5054–MAX5057 have internal undervoltage lockout for VDD. When VDD is below the UVLO thresh- old, OUT_ is low, independent of the state of the inputs. The undervoltage lockout is typically 3.5V with 200mV typical hysteresis to avoid chattering. When VDD rises above the UVLO threshold, the outputs go high or low depending upon the logic-input levels. Bypass VDD using low-ESR ceramic capacitors for proper operation (see the Applications Information section). Logic Inputs The MAX5054B–MAX5057 have TTL-compatible logic inputs, while the MAX5054A is a CMOS logic-input dri- ver. The logic-input signals can be independent of the VDD voltage. For example, the device can be powered by a 5V supply while the logic inputs are provided from CMOS logic. Also, the logic inputs are protected against the voltage spikes up to 18V, regardless of the VDD volt- age. The TTL and CMOS logic inputs have 300mV and 0.1 x VDD hysteresis, respectively, to avoid possible dou- ble pulsing during transition. The low 2.5pF input capaci- tance reduces loading and increases switching speed.
