MAX5056BASA+T

Overview

The MAX5056BASA+T is a dual MOSFET gate driver manufactured by Analog Devices under the Maxim Integrated brand. It operates within a supply voltage range of 4 V to 15 V and delivers a peak output current of 4 A per channel. The device features symmetric propagation delays of 20 ns, with rise and fall times of 85 ns and 75 ns respectively. It supports inverting logic configurations and functions across an industrial temperature range from -40°C to +125°C. Packaged in an 8-pin SOIC, it draws a typical operating supply current of 2.4 mA.

Feature Summary

• Dual-channel architecture providing independent high-current drive for two MOSFETs
• Ultra-fast switching performance with 20 ns propagation delay for minimal power loss
• Robust 4 A peak output capability ensures rapid charging and discharging of gate capacitance
• Compatible with standard TTL logic input levels for direct microcontroller interfacing

Applications

• High-frequency synchronous buck and boost converter topologies
• Half-bridge and full-bridge motor drive circuits
• Isolated power supply primary side driving stages
• Class-D audio amplifier output stages requiring fast edge rates

Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm package integrity upon receipt as surface-mount devices are sensitive to handling. Ensure ESD precautions are strictly followed during storage and assembly. Cross-reference datasheet revisions to confirm pinout compatibility with existing designs. Validate thermal performance under maximum load conditions before final implementation.

Selection Notes

Select this component when simultaneous dual-channel isolation or compact footprint is required. The 4 A drive strength suits medium-power applications where efficiency depends on low switching losses. Consider the inverting configuration if logical signal inversion aligns with control scheme requirements. Evaluate thermal dissipation capabilities given the 471 mW power rating in the SOIC-8 package.

Part Context

This part belongs to the MAX5055/MAX5056 family of dual MOSFET drivers designed for high-speed switching applications. It shares architectural similarities with single-channel variants but offers integrated dual-drive functionality. The series targets power management ICs within the broader PMIC category, emphasizing speed and reliability over ultra-low quiescent current consumption found in other regulator families.

Replacement Considerations

MAX5055BASA+T serves as a functional substitute within the same product family offering identical drive characteristics and pinout compatibility.
