19-3348; Rev 0; 8/04 www.DataSheet4U.com 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 Features MAX5054–MAX5057 Ordering Information PART MAX5054AATA MAX5054BATA MAX5055AASA MAX5055BASA MAX5056AASA MAX5056BASA MAX5057AASA MAX5057BASA TEMP RANGE -40°C to +125°C -40°C to +125°C -40°C to +125°C -40°C to +125°C -40°C to +125°C -40°C to +125°C -40°C to +125°C -40°C to +125°C PINPACKAGE 8 TDFN-EP* 8 TDFN-EP* 8 SO-EP* 8 SO 8 SO-EP* 8 SO 8 SO-EP* 8 SO TOP MARK AGS AGR — — — — — — Applications Power MOSFET Switching Switch-Mode Power Supplies DC-DC Converters Motor Control Power-Supply Modules Typical Operating Circuit VIN VOUT *EP = Exposed pad.
