MAX5056BASA

Overview

The MAX5056BASA is a dual high-speed MOSFET driver from the Maxim Integrated portfolio, designed for efficient switching control. It features a 4A peak output current capability and a fast 20ns propagation delay with matching rise and fall times. The device operates within a supply voltage range of 4V to 15V and supports TTL logic inputs. It is housed in an 8-pin SOIC package and functions as an inverting driver configuration.

Feature Summary

• Provides dual independent channels for driving N-channel MOSFETs with high peak current sourcing and sinking capabilities.
• Ensures precise timing synchronization through matched propagation delays and symmetric rise/fall times.
• Compatible with standard TTL logic input levels for direct interfacing with microcontrollers or logic circuits.

Applications

• Synchronous rectification in DC-DC converters
• High-frequency motor control systems
• Power management modules requiring fast switching

Procurement Notes

Verify the specific suffix (e.g., +T) for tape-and-reel packaging requirements against your assembly needs. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the SOIC-8 footprint matches your PCB layout constraints. Cross-reference the latest datasheet revision for any pinout or electrical characteristic updates before finalizing procurement.

Selection Notes

Select this component when dual-channel isolation and minimal propagation delay are critical for system efficiency. The 4A drive strength suits medium-power applications, while the 4V–15V supply range offers flexibility. Consider thermal dissipation limits in dense layouts. Verify that the inverting logic configuration aligns with the control signal polarity required by the target power stage design.

Part Context

This part belongs to the MAX505x series of dual MOSFET drivers, which emphasizes speed and drive strength. It shares functional similarities with the MAX5054 and MAX5057 but differs in specific package options and minor electrical parameters. The series targets applications demanding reliable, high-speed switching without complex external timing components.

Replacement Considerations

The MAX5054 serves as a functional substitute within the same family. Verify compatibility regarding package dimensions and exact propagation delay specifications. Ensure the replacement part meets the same 4A output current requirement and TTL input compatibility for seamless integration into existing designs.
