MAX5056AASA-T

Overview

The MAX5056AASA-T is a dual low-side MOSFET gate driver manufactured by Analog Devices Inc./Maxim Integrated. It provides up to 4A peak source and sink current per channel, enabling fast charging and discharging of large gate capacitances typical of power MOSFETs. The device operates with non-inverting logic inputs and features a supply voltage range of 8V to 12.6V. Key electrical parameters include a propagation delay of 20ns, rise/fall times of 20ns, and an operating temperature range from -40°C to +125°C. It is housed in an 8-pin SOIC-EP package.

Feature Summary

• Delivers high peak drive current for rapid switching
• Optimized for driving large power MOSFET gate capacitances
• Features low propagation delay for high-speed applications

Applications

• Power supply designs requiring efficient MOSFET control
• Industrial motor drive systems
• High-frequency DC-DC converter topologies

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'T' indicates tape-and-reel packaging if required for automated assembly. Check for obsolescence status as this part may be discontinued or subject to limited availability. Ensure the 8-SOIC-EP footprint matches your PCB design constraints before procurement.

Selection Notes

Select this driver when high peak current is necessary to minimize switching losses in power stages. The non-inverting configuration simplifies control logic interfacing. Consider the thermal performance of the exposed pad (EP) package for heat dissipation in dense layouts. Verify that the input signal levels are compatible with the 8V–12.6V supply range.

Part Context

This component belongs to the Maxim Integrated line of power management ICs, specifically within the MOSFET gate driver category. It is designed to interface between low-voltage control logic and high-power switching elements. The series focuses on efficiency and speed, targeting applications where rapid transitions are critical for system performance and thermal management.

Replacement Considerations

Public sources indicate the MAX5056AASA variant is obsolete. Potential substitutes should offer similar 4A peak current, dual low-side configuration, and 8-SOIC-EP packaging. Verify pin compatibility and electrical specifications against original datasheets before substitution.
